The Eighth Call for Proposals for XMM-Newton closed in October 2008; successful submissions were announced on December 17, 2008. The Budget Process has begun, as the deadline was March 20, and results are expected by June 2009. Accepted proposals may be found online at http://xmm.esac.esa.int/external/xmm_news/otac_results/index.shtml . It is anticipated about 30% of category C targets will be scheduled.
The XMM-Newton Science Operations Centre is organizing a workshop for May 18-20, 2009, in Madrid, Spain, entitled "Supersoft X-ray Sources - New Developments". The goal of the workshop will be to review the current status of observational and theoretical research on supersoft X-ray sources and identify the most important unresolved problems. More information regarding the meeting location and accommodations, as well as the submitted abstracts, may be found here: http://xmm.esac.esa.int/external/xmm_science/workshops/2009_science/.
The fourth International Astronomical Consortium for High Energy Calibration (IACHEC) meeting took place in Japan during April 27-29, 2009. The results of investigations into the cross-calibrations of XMM-Newton, Chandra, and Suzaku were discussed; the presentations are available in pdf format at http://www.iachec.org/meetings/2009/. The presentations from the XMM-Newton Users Group Meeting, which took place May 6-7, 2009 and focus on instrument calibration and software, are also available at http://xmm.esac.esa.int/external/xmm_user_support/usersgroup/20090506/index.shtml.
The number of publications using XMM-Newton data continues to increase, as does the rate at which they are published. As of the end of March, 2009, over 2300 refereed papers have been published making use of XMM-Newton; 444 of these came over the past year. The publication rate from April 2008 through March 2009 averaged a remarkable 111 papers per quarter -- this compares very well with previous years (2004-2006: 81 papers per quarter; 2006-March 2008: 100 papers per quarter). XMM-Newton's Educator Ambassadors continue to bring the satellite and its data into the classrooms by presenting workshops using XMM-Newton educational materials. Recent workshops were held at the NSTA National Conference in New Orleans, LA, and at the Independence Public Library in Kansas, as part of the "Visions of the Universe" NASA-sponsored exhibit.

The spacecraft and payload continue to operate nominally with one exception: on 19 February 2009 detector #5 of the SPI instrument failed for unknown reasons. Besides a reduction in the effective area of SPI, this loss has no major effect. The latest SPI annealing took place successfully from 20 April to 10 May 2009.
The call for observing proposals in the AO-7 cycle was closed on 20 February with 76 proposals received. Under the new scheme recommended by the IUG all non-TOO proposals are open for sharing via data-rights proposals under certain conditions. The call for these proposals opens on 25 May with proposals due by 3 July. See http://integral.esac.esa.int for more information.
AO-6 observations continue routinely. TOO observations were done on the blazar PKS 1510-089 following a flare as reported by FERMI and on the magnetar 1E 1547.0-5408, which showed SGR-like bursts. The latter was followed by the whole family of high-energy observatories and first results are appearing in the literature.
Some of the recent scientific highlights include:
The total number of refereed publications using INTEGRAL scientific data is 449, with 41 papers in 2009 (up to end of March).

The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) awaits the delayed emergence of the new Solar Maximum before attempting a second anneal of its germanium detectors. It continues to study the quiet Sun at hard x-ray energies (above 3 keV) and to function as an omnidirectional detector in the 50 keV to 20 MeV range, despite reduced sensitivity due to radiation damage. Interested readers are referred to the ongoing series of RHESSI nuggets ( http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets ) for recent results and ideas on solar and non-solar topics. The 100th nugget, recently published, describes the origin and history of the mission.

All instruments on board Swift continue to operate in good health. As of early May, Swift has observed 467 Gamma-Ray Bursts of which 426 were discovered by Swift. The TOO requests have greatly increased over the past months as a results of the communities strong interest in using Swift's multi-wavelength and fast response capabilities.
The deadline for submitting Notice of Intents for the Swift Cycle 6 Guest Investigator program is September 16 and the deadline for submitting Cycle 6 science proposals is October 28, 2009. As during previous cycles, observing time will be made available to scientists at U.S. and non-U.S. institutions to study persistent and transient astrophysical sources in Cycle 6. In addition, funds will be made available to U.S. scientists for theoretical GRB investigations that will advance the mission return of Swift and to conduct correlative GRB observations at other wavelengths. Details of the Cycle 6 program elements are given in NASA's Research Opportunities in Space and Earth Sciences (ROSES) 2009 and on the Swift web site ( http://heasarc.gsfc.nasa.gov/docs/swift/swiftsc.html ).
On April 23, 2009, the Burst Alert Telescope on board Swift triggered on a ~10 sec duration burst with an X-ray but no optical counterpart. Rapid ground-based IR follow-up observations of GRB 090423 measured a redshift of z=8.2, which makes this burst the most distant known object in the universe, arising from an exploding star more than 13 billion light years away. The previous record holder was a burst at z=6.7 that was seen by Swift in September 2008. GRB 090423 is almost 200 million light years further away and occurred when the universe was only about 630 million years old.
Swift Educator Ambassadors are supporting the International Year of Astronomy by conducting workshops in conjunction with the "Visions of the Universe" exhibit, which is appearing at 40 different libraries located in primarily rural areas. This exhibit, and special NASA-funded workshops, is bringing the excitement of astronomy into regions that usually do not see NASA personnel. One recent workshop was featured in a local newspaper from Marion Indiana.

The RXTE team is delighted to announce that the RXTE mission has been extended for another year (Oct. 2009 - Sept. 2010). Observing proposals will be solicited for RXTE Cycle 14, for observations in 2010. It is expected that proposals will be due in late summer 2009. More information will be announced on the RXTE web site and the 'xtenews' mailing list once plans are finalized.
The RXTE PCA team is finalizing a new version of the PCA response matrix. This release will contain a new version of PCARMF (version 11.6), as well as updated calibration files available from CALDB. The new release will especially improve spectral fits for PCA data taken after the year 2002, thanks largely to a revised energy to channel gain calibration conducted by Nikolai Shaposhnikov. The new gain calibration allows spectral fitting down to 2.5 keV reliably during the PCA mission. It is expected that the software will be released this summer, together with a report on the new results, available from the RXTE PCA Digest page http://heasarc.gsfc.nasa.gov/docs/xte/pca_news.html ).
RXTE continues to discover new sources and new source behaviors. Watts reports the discovery of oscillations for the first time in a thermonuclear burst from the millisecond X-ray pulsar HETE J1900.1-2455, at a frequency just below the known pulsar frequency of 377 Hz (ATEL #2004). The new INTEGRAL source IGR J19294+1816 was found to have pulsations at 12.4 seconds (ATEL #2002). Leahy et al. (2009) report constraints on the equation of state of the millisecond X-ray pulsar XTE J1814+338 based on pulse shape fitting, which are consistent with a stiff equation of state for nuclear matter. The ASM light curve of 4U 1210-64 reveals a significant modulation at a period 6.7 days, which is suggestive of its orbital period (ATEL #1861).
The HESS and Fermi LAT collaboration report on joint optical-TeV observations of the blazar PKS 2155-304, including RXTE monitoring in the X-ray band (2009). The observations revealed a correlation between X-ray flux and very high energy spectral index, but an unexpected lack of correlation between X-ray and very high energy gamma-ray fluxes, which is at odds with the usual synchrotron self Compton emission models. After a five year monitoring campaign using RXTE and optical data, Breedt et al. (2009) found correlated X-ray and optical emission from the Seyfert galaxy Markarian 79. On short time scales the optical emission is consistent with reprocessing of the X-ray emission in an optically thick accretion disk.

Suzaku began observing AO-4 targets in April, selected from proposals submitted to JAXA, NASA, and ESA. PIs of proposals submitted to NASA have now received individual evaluations, and successful US PIs now have the opportunity to apply for funding. However, due to a substantial decrease in available funds, NASA HQ does not intend to fund proposals with only priority C targets in this round.
The international Suzaku project has approved the initiation of 4 Key Projects on highly magnetic neutron stars, the Galactic bulge X-ray emission, Kepler's supernova remnant, and on the relativistic Fe K line in AGN. The project has committed 2 Ms of observing time during the AO-4 period, and the respective PIs will be invited to argue for the continuation of these projects in early 2010, in competition with new Key Project proposals that may be submitted.
The third Suzaku special issue of Publications of the Astronomical Society of Japan is now in print, and Suzaku papers are appearing in other peer-reviewed journals in increasing numbers. We have now added bibliographic links from the "suzamaster" table in Browse to the ADS, and from the ADS to the Suzaku sequence that the paper is based on. If you find mistakes or omissions, please contact the Suzaku GOF.

The Fermi Gamma-ray Space Telescope has now been surveying the gamma-ray sky for more than six months, and operations continue to be smooth.
Some early science highlights:
Some notes from the Fermi Science Support Center:
The Fermi Project has a new Project Scientist, Julie McEnery (Goddard). Steve Ritz is moving from Goddard to the University of California, Santa Cruz. With sorrow we report the passing of David Band, a key member of the FSSC. David's role in the development of gamma-ray burst astrophysics will be remembered every time a gamma-ray burst spectrum is modeled with a Band Function. Fermi helped fund the production of seven From Earth To The Universe (FETTU) museum quality free-standing displays, which were designed by the NASA Education and Public Outreach (E/PO) group at Sonoma State University. The displays are now making their way around the San Francisco Bay Area at various colleges, museums, and public events in celebration of the International Year of Astronomy. This has been in addition to the E/PO's regular workshops, lectures, and other normal Fermi-related outreach.
Important upcoming Fermi mission activities (exact dates to be announced):

NuSTAR, the Nuclear Spectroscopic Telescope Array, is a NASA Small Explorer (SMEX) mission which will do targeted observations in the 6 to 79 keV hard X-ray window. As the first focusing hard X-ray telescope on-orbit, NuSTAR will have more than 100 times the sensitivity of any previous mission at these energies.
NuSTAR continues to be on track for launch in August 2011. The project is now in Phase B, or the definition phase, and preparing for the Preliminary Design Review (PDR) in early June. The Key Decision Point C (KDP-C), or confirmation review, will be in early August.
As of February, the NuSTAR launch system has been announced. NuSTAR will launch into a low Earth orbit on a Pegasus XL rocket, built by Orbital Space Corporation, from Kwajelein Atoll. Kwajalein, which is in the Marshall Islands in the South Pacific, is the world's largest coral atoll and will allow NuSTAR to have a near-equatorial (6 degree inclination) orbit. This orbit will minimize passage through the South Atlantic Anomaly, thus minimizing the radioactive background for NuSTAR.
Preliminary response files for simulating NuSTAR observations will be available to the community through the HEASARC after the PDR.

Approximately 200 members of the IXO Science team braved cold and icy weather at the end of January in Boston to discuss the IXO science case. The presentations were largely based on the White Papers which were submitted to the Decadal ASTRO2010 Science Frontier Panels on Feb 15 2009. These White Papers can be found on the newly re-vamped IXO web site at http://ixo.gsfc.nasa.gov/resources/presentations/ (scroll down to February 2009). Presentations from the January Boston meeting can also be found on this site (scroll down to January 2009). Approximately 100 Boston area astronomers enjoyed much more pleasant weather in order to attend an Astro2010 Town Hall meeting hosted in part by the local IXO team. The minutes from this Town Hall will shortly appear on the Astro2010 web site.
Also in support of the Decadal process, the IXO team submitted a response to the Request for Information from the panels. This document briefly discusses the IXO science as described in the White Papers, and also discusses the mission implementation and technical readiness. It too can be seen on the IXO web site.
Members of the core IXO science team have made a concerted effort to give colloquia on the IXO at Universities and Research Centers this spring. If you are interested in such a colloquium, please contact the author of this article and we will endeavor to please! We have a set of slides for the one hour talk which are available for the asking, should you want or need them.

The last few months saw several conferences and workshops of particular relevance to LISA and LISA-related astrophysics. The American Physical Society meeting, held in Denver on May 2-5, covered a wide swath of gravitational-wave astronomy, with several dozen papers on theoretical and experimental topics spanning the entire gravitational wave spectrum. There were over a dozen LISA-specific contributions, including a standing-room only contributed session on LISA, three invited talks on LISA science and technology, as well as several other invited talks that discussed aspects of LISA-related physics and astrophysics.
The Intermediate Mass Black Hole (IMBH) workshop held at the University of California, Irvine, on April 1-3, 2009, spotlighted some of the exciting developments in the field. The search for IMBHs is ongoing, via direct evidence from electromagnetic signatures of accretion onto IMBHs, and indirect comparisons of the observed structure of globular clusters with numerical simulations of cluster dynamics with or without an IMBH. At the same time, the workshop emphasized the variety of open questions, ranging from IMBH formation channels to the role of IMBHs in early cosmological history to the possible rates of IMBH coalescences in galaxy mergers. LISA's ability to detect gravitational waves from binary inspirals involving intermediate-mass black holes was highlighted as a unique probe for exploring some of these questions. Slides for the workshop talks can be seen at http://www.physics.uci.edu/IMBH/agenda.html .
The Mar 30-Apr 1 conference on the "Observational Signatures of Black Hole Mergers" at the Space Telescope Science Institute brought together a diverse group of observational and theoretical researchers to discuss recent observations of candidate black-hole merger systems, as well as future opportunities for both space- and ground-based observations. LISA observational capabilities featured prominently in many talks, for which streaming video is available at http://www.stsci.edu/institute/itsd/information/streaming/archive/OSBHM2009 .
The fourth round of "mock LISA data challenges" (a community-wide program to demonstrate and develop LISA data-analysis capabilities) was completed at the end of April. The latest challenge included signals from chirping Galactic binaries, spinning black holes, extreme--mass-ratio inspirals (EMRIs), cosmic-string bursts, and cosmological stochastic backgrounds. The response from the community (17 entries) was very strong: although evaluation is in progress, it is already clear that there are very good entries in every source category. For instance, multiple groups did a very good job detecting and recovering parameters for all spinning black hole binaries; several groups tackled the EMRIs, which were recovered for signal-to-noise ratios as low as 19 (quite below the conservative threshold of 30 usually assumed in the literature). A wide variety of techniques was applied to the challenge, including Markov Chain Monte Carlo, nested sampling, and genetic algorithms. A full report will be presented at the Amaldi Conference on gravitational waves June, when the data sets for the next challenge will also be released. For full details and references, see the official challenge site, http://astrogravs.nasa.gov/docs/mldc .

Description: APT3 summarizes recent results from high energy astrophysics observations with the main focus on space based satellites and observatories. The session primarily highlights observations from missions such as CHANDRA, XMM-Newton, Suzaku, Swift, FERMI, and Integral which are related to science involving strong gravity environments as found near neutron stars and black holes but also gravity environments on large scales such as clusters of galaxies. The session also includes science programs proposed for future missions.
Particle astrophysics is now a busy intersection between particle physics, astrophysics and cosmology. In 2009, the Large Hadron Collider will begin taking data and start its exploration of the TeV scale and physics beyond the Standard Model. The Fermi Gamma-ray Space Telescope (FGST) launched in June 2008, and it will have passed its one year anniversary by the time of the conference. Many results have already been reported, and there will be considerably more by the time of the conference. We expect more interesting results from Pamela and ATIC. In addition, ground-based gamma ray telescopes including HESS, MAGIC, VERITAS, MILAGRO and ARGO have been observing gamma-rays at the TeV scale and higher with unprecedented accuracy for years. We also expect new exciting results from Auger. Neutrino experiments such as Antares and IceCube are starting to run at similar and higher energies. Underground experiments that focus on dark matter direct detection, neutrino mass measurement, and gravitational wave detection, are all making rapid progress. This conference aims to understand what we can learn from the present and upcoming observational results from both the LHC and a broad range of astrophysical searches. It will provide an occasion for theorists and experimentalists to discuss the latest and upcoming results in these fields, to consider new strategies, technologies and collaborative efforts to address some of the most pressing questions in physics today, including the nature of dark matter and the origin of cosmic rays.
The website is active and has detailed information.
Brief announcement: The 3rd International Summer School on Astroparticle Physics (NIJMEGEN09) is intended for graduate students and postdocs working (or starting to work) in this new interdisciplinary research domain emerging at the interface of physics and astronomy. The School will provide a fairly comprehensive coverage of modern theoretical and observational developments in astroparticle physics. Topics include: Cosmology, Cosmic Microwave Background, Gravitational Waves, Neutrinos, Ultra-High Energy Cosmic Rays, Dark Matter, and Dark Energy. Lectures are given in the morning while the afternoons are reserved for a special training project aimed at acquiring skills in presenting, defending and reviewing modern research proposals in astroparticle physics. The programme includes social activities and two evening lectures, presented by the distinguished scientists Gerard 't Hooft and Heino Falcke. Participation is limited to about 75 students. The working language is English. The deadline for registration is July 1st, 2009.
The Chandra Calibration Review is held in order to disseminate and advance our understanding of the performance and capabilities of the Chandra X-ray Observatory. It is intended to share the Chandra teams' knowledge of the detectors, gratings, mirrors, and aspect system with the community while encouraging participation and feedback in the process of calibrating the observatory. Abstracts are solicited on various aspects related to Chandra calibration. This year it will be held in conjunction with Chandra's First Decade of Discovery event.
This will be the fifth in a series highlighting unique imaging and spectroscopic results from NASA's Chandra X-Ray Observatory. This event will highlight key science results from the first ten years of operation of the Chandra X-ray Observatory. The focus will be on results which have had the largest impact of Astrophysics, including: The Cosmic Evolution of AGN, AGN outflows, evolutionary processes in galaxy cluster, our understanding of normal galaxies including our own Galactic center. More locally, high resolution studies of compact objects, supernova remnants and star forming regions have lead to changes in our understanding of the stellar life cycle. We will also cover recent results from the XMM-Newton, Suzaku, Swift, INTEGRAL, RXTE and AGILE missions, as well as related theoretical results.
The Symposium will include invited talks plus oral and poster contributions. The number of slots for oral presentations is limited. However, we will highlight the Posters via long breaks, with coffee and refreshments in the Poster rooms. Also, there will be an opening reception Monday evening, and a Poster viewing session Tuesday evening, both with food and drinks.
Abstracts Requesting an Oral Presentation: 10 July
Final Abstract Deadline: 21 August
Hotel Reservation Deadline: 21 August
Registration Closes: 4 September
The most current information on the Chandra Decade meeting can be found on the web site http://cxc.harvard.edu/ChandraDecade/index.html .
Cosmology is one of the most active fields of astronomy. It inspires scientists in the neighboring fields as well as the general public. In the last decade, the discovery of cosmic acceleration (and thus the need for dark energy) fostered the attention of many scientists on this branch of astrophysics. Recent progress in studying the large-scale structure of the universe and the physics of the intergalactic medium is strongly driven by the advent of multi-object spectrographs on large aperture telescopes. Advances in cosmology in general will also build on wide-field imaging, as put in place in major upcoming surveys, as well as new space telescopes, covering the electromagnetic spectrum from radio to X-rays, gamma-rays and more messengers.
In the International Year of Astronomy and with Planck having delivered first data by then, it is timely to hold a splinter meeting at the AG-Tagung on the recent progress and future perspectives in cosmology from observations, simulations and theory.
Particle acceleration in shocks is the cornerstone of our interpretation of many nonthermal astrophysical sources. Due to the intrinsic plasma nonlinearities, the acceleration process and its associated phenomena, such as the generation of magnetic fields, are notoriously difficult to unravel. However, the influx of new data and the development of new numerical and analytical tools make it an opportune time to reconsider the progress. This conference will address recent achievements and challenges in understanding nonlinear phenomena associated with astrophysical plasmas. The subjects will include:
(This is a conference associated with the KITP program on Particle Acceleration in Astrophysical Plasmas)
The Workshop is aimed at providing an overview of the most relevant recent discoveries in gamma-ray astrophysics, with particular emphasis on the current gamma-ray missions (AGILE and FERMI) and on the related radio, optical, X-ray and TeV observations of cosmic sources. We will focus also on how to strengthen the multifrequency response to alerts originating from the gamma-ray experiments.
Talks will cover several topics including:
* High energy properties and modelling of AGNs with emphasis on the brightest gamma-ray blazars;
* Our Galaxy: high-resolution gamma-ray observations and diffuse emission;
* Pulsars and pulsar wind nebulae;
* Microquasars, Galactic compact objects and unidentified transients;
* Colliding Wind Binaries;
* Terrestrial Gamma-Ray Flashes.
A special session will be devoted to the discussion of current and future
multifrequency programs for the AGILE and FERMI missions.
The Xenia team would like to invite you to participate in a workshop on "Cosmic Chemical Evolution: Probing Abundances and Structure Evolution from the dark ages to the present", October 5-7, 2009 at quaint St. Michael's, (http://www.stmichaelsmd.org/ ). The meeting will focus mainly on the use of Gamma Ray Bursts and Galaxy Clusters as probes of the structure of the Cosmic Web, from the epoch of the first stars and galaxies, throughout the era of cluster formation to the cosmic filaments in the present era. In addition the workshop will address a wide variety of topics of chemodynamics with emphasis on galactic evolution, feedback processes, Supernova Remnants, as well as on searches for light dark matter and counterparts for gravitational waves.
We have reserved a block of 60 rooms at Harbourtowne Resort and Conference Center ( http://www.harbourtowne.com/ ) until roughly one month prior to the meeting at a package deal. All participants will be required to make their own reservations. More information on the meeting will appear by the end of May at the Xenia mission URL ( http://sms.msfc.nasa.gov/xenia/ ).
For the Xenia team
In the present Universe, the majority of supermassive black holes in galactic nuclei are in a low-luminosity state. Understanding the physical nature of this state and its connection to the nuclear environment is central to the study of galaxy structure and evolution. The Galactic Center Workshop 2009 will be devoted to the presentation and discussion of recent observational and theoretical results on low- luminosity galactic nuclei. In particular, the center of the Milky Way will be emphasized to give a close-up view of such a nucleus, resolving structures from scales of hundreds of parsecs down to a few milliparsecs, and thus to explore the implications for our understanding of other galactic nuclei. Developments in the study of low-luminosity galactic nuclei in nearby galaxies will also be highlighted to provide complementary perspectives -- global and relatively unobscured -- which are particularly important for investigating the relationship between nuclear activity and the galactic "eco-system".
The workshop is aimed to address a range of scientific topics related to SMBHs
and galactic nuclear environment:
* PHYSICAL AND CHEMICAL PROCESSES IN THE CENTRAL MOLECULAR ZONE
* STAR FORMATION IN CIRCUMNUCLEAR REGIONS
* STELLAR DYNAMICS IN THE PRESENCE OF THE GALACTIC BLACK HOLE
* THE SUPERMASSIVE BLACK HOLE: ACCRETION, SPIN AND STRONG GRAVITY
* HIGH-ENERGY DIAGNOSTICS OF GALACTIC NUCLEAR ACTIVITY
* SMBH AND STELLAR FEEDBACK ON THE NUCLEAR ENVIRONMENT
In addition, we propose to have daily discussions/mini-debates to focus on persistent issues facing GC studies and to raise new challenging questions. The preliminary plan is to solicit and post a set of issues to be discussed and debated so that interested individuals can get prepared.
The conference will be held at the Good Hope Hotel, which is close to the headquarters of the Shanghai Astronomical Observatory. It is located in one of the major commercial centers of Shanghai, so there are various restaurants and bars nearby. The workshop will cover 5 days, October 19-23, with a 4.5 full-day science program. A half-day tour (Wed 21 afternoon) will be arranged to the small ancient town of Zhu-Jia-Jiao in the suburb of Shanghai and to visit the Bund. The banquet will be held that evening on a tour boat on the Huang-Pu river, with sightseeing after the banquet along the Bund.
More information is available on the workshop website, http://www.shao.ac.cn/gc2009/
The 2009 Fermi Symposium is dedicated to results and prospects for scientific exploration of the Universe with the Fermi Gamma-ray Space Telescope and related studies. The symposium comes shortly after the Fermi data release, offering an opportunity for the astrophysical community to share in the excitement of discoveries being made with the Fermi instruments. Topics include: blazars and other active galactic nuclei, pulsars, gamma-ray bursts, supernova remnants, diffuse gamma radiation, unidentified gamma-ray sources, and searches for dark matter. The meeting will be held in downtown Washington, D.C,. near the U.S. Capitol Building.
The idea of this meeting is to bring together scientists who have worked with Swift data in the last 5 years to talk about science results and discuss strategies for the future. Swift has become one of NASA's most successful mission. Although Swift's primary task still is to observe Gamma-Ray Bursts, it is one of the most versatile missions ever flown. With its multiwavelength and fast scheduling capacity it is ideal for multiwavelengths and/or monitoring programs. Because of this it has been used for AGN, supernovae, variable stars, transients, comets, etc. Swift has observed the closest objects (comets) and with GRB 050904 and 080913B some of the most distant objects in the Universe. By 2009 we will also have new opportunities for Swift with increasing capacities in the GeV and TeV energy ranges with FERMI, AGILE VERITAS, MAGIC and HESS, and by gravitational wave detectors such as LIGO, VIRGO and GEO.
We will have a mixture of invited talks and contributed talks and posters aiming for roughly 100-120 participants. We will send out further announcements including webpages about this meeting in the future.
The 10th anniversary of the three currently active X-ray spectrometers on XMM-Newton and Chandra is taken as an opportunity to organize for 2010, at the historic main university 'Academy Building' in Utrecht, an international conference highlighting the state of the art and future prospects of high-resolution astrophysical X-ray spectroscopy. The first announcement will be made around July 1st, 2009, with an abstract deadline in November. Stay tuned to the conference web site: http://www.sron.nl/xray2010/
