from the editor into your mailbox.
The newsletter itself can be found online at
http://www.aas.org/head/headnews/headnews.may09.html.
Contact information for all current HEAD Executive Committee members may be found at the end of this newsletter.
The next HEAD meeting will be March 1-4, 2010 at the Hilton Waikoloa Village on Hawaii's Big Island. Details are becoming available at the Conference Connection website: http://www.confcon.com/head2010/. Please send suggestions for invited speakers to HEAD EC members ASAP as we will choose the invited speakers during the summer. Please remember that there is a new HEAD dissertation prize which will be awarded for the first time at the 2010 HEAD meeting. Those who have received their degrees within 3 years prior to the HEAD meeting date, in this case since March 1, 2007, are eligible for the prize.
Here is a reminder about upcoming HEAD deadlines (all submissions are via email):
- October 1, 2009: Schramm Prize applications due to HEAD press officer Megan Watzke
- October 1, 2009: HEAD 2010 Meeting Special Session proposals due to HEAD secretary
- October 15, 2009: Rossi Prize Nominations due to HEAD secretary
- October 15, 2009: HEAD Dissertation Prize nominations due to HEAD secretary
The HEAD Executive Committee is considering a few changes. These include a possible increase in dues,
a possible lengthening of the terms of HEAD EC members from 2 years to 3 years, and a change from
email voting to a more secure web-based voting scheme. The term length and voting change both are
bylaw changes that must go through a formal process of notification of the membership and the AAS council.
We are now soliciting input from members regarding all these changes. Please notify your HEAD EC members
with your perspectives on these issues.
POSSIBLE INCREASE IN HEAD DUES
It has been several years since the last increase in dues from $8 to $10 and the HEAD EC is considering
an increase from $10 to $20 while retaining the dues for junior AAS members at $10. The reason the HEAD EC
is considering the dues increase is to shore up the HEAD financial reserves for awarding prizes.
Here is a detailed breakdown: HEAD has had $30K--$45K in its accounts the last few years (currently we
have $45.4K as of April 2009).
HEAD's money is invested as part of the overall AAS financial reserves in a conservative manner. The AAS, as a non-profit,
seeks to operate within 4% of its financial reserves. The HEAD annual expenses are for the Rossi prize ($1500 + ~$300 for
a certificate), the Schramm prize ($1000 + ~$200 for a certificate), the dissertation prize ($670 + $200 for a certificate).
For the Schramm and dissertation prizes, we assume the prize is awarded every 18 months at the time of the HEAD meeting and
have prorated the $1500 and $1000 prize amount accordingly. There are also some nominal expenses for HEAD EC meetings each
year ($500). This total is approximately $4.4K for HEAD expenses each year. Thus, it is advisable for HEAD to have financial
reserves of $110K.
The HEAD EC is thus working on a strategy to increase the financial reserves to guarantee we will be able to support the
HEAD prizes. For comparison, the AAS Division of Planetary Sciences (DPS), which is just slightly larger than HEAD (~960 full members + 500 division-only members
versus the ~950 members in HEAD), carries a financial reserve of $200K.
The HEAD EC is considering a number of possible strategies, likely to be implemented in a multifaceted approach. These include a possible dues increase (already mentioned) as well as a
possible 'Campaign for HEAD Prizes' in the 2010 membership statement so that tax-deductible contributions may be made for
the HEAD prizes. We are also looking at strategies whereby highly successful HEAD meetings may bring funds back to HEAD for
the HEAD prizes. The HEAD Executive committee welcomes your comments on all these prospective changes.
HEAD Bylaw Changes
Three changes are being proposed to the bylaws. These bylaw changes must first be approved by the AAS council at its meeting in June 2009, then discussed at the HEAD annual business meeting in January 2010, and finally put to a vote of the entire HEAD membership in January 2010 after that discussion.
- Removing the email requirement for HEAD voting
- CURRENT STATUS: Currently HEAD voting is done by email to the
HEAD Secretary-Treasurer. The secretary checks these emails and
determines the outcome.
- PROBLEM: This method does not provide a secret ballot, is not
particularly secure, and is cumbersome for the secretary-treasurer.
- SOLUTION: We wish to change the language of the by-laws to read
"voting by electronic means". This will enable HEAD to use the AAS
website for voting (a secure site that provides a secret ballot vote) but also
allows for future voting technologies besides web voting.
- Removing the outdated "transferral of abstracts" text
- CURRENT STATUS: There is language in the HEAD bylaws stating that
5 days after a HEAD meeting, the HEAD secretary-treasurer will transfer
the abstracts to the AAS.
- PROBLEM: The abstracts are handled by the AAS and no such transfer is
required. This text is outdated.
- SOLUTION: Remove this text from the bylaws
- Extend HEAD Executive Committee terms to 3 years
- CURRENT STATUS: The HEAD committee members who are not
officers serve for 2 years.
- PROBLEM: By the time HEAD EC members are "trained", they are
rotating off the committee. HEAD meetings occur every 1.5-2 years so
committee members serve during only one HEAD division meeting. For
comparison, terms for DPS and Council members are 3 years, not 2.
- SOLUTION: Extend the terms to 3 years. To preserve the current size of
the HEAD committee, we will elect 2 new members each year instead of 3.
In anticipation of the January bylaw change, the 3 new members who
will be elected in December will be initially invited to serve 2-year terms
to be extended to 3-year terms after the bylaw change is adopted (all
candidates will be apprised of the likely changes).
All HEAD members must maintain an up-to-date email address with the AAS to ensure that society email (including ballots for elections) reaches them. To change your email address with the AAS please visit http://www.aas.org and follow the member log-in links.

2. David Band (1957-2009)
David L. Band, of Potomac Maryland, died on March 16, 2009 succumbing to a long battle with spinal cord cancer. His death at the age of 52 came as a shock to his many friends and colleagues in the physics and astronomy community.
David showed an early interest and exceptional aptitude for physics, leading to his acceptance at the Massachusetts Institute of Technology as an undergraduate student in 1975. After graduating from MIT with an undergraduate degree in Physics, David continued as a graduate student in Physics at Harvard. His emerging interest in Astrophysics led him to the Astronomy Department at the Harvard Smithsonian Center for Astrophysics (CfA), where he did his dissertation work with Prof. Jonathan Grindlay. His Ph.D. (Physics) thesis in 1985 entitled "Non-thermal Radiation Mechanisms and Processes in SS433 and Active Galactic Nuclei" was "pioneering work on the physics of jets arising from black holes and models for their emission, including self-absorption, which previewed much to come, and even David's own later work on Gamma-ray Bursts", according to Josh Grindlay who remained a personal friend and colleague of David's. Following graduate school, David held postdoctoral positions at the Lawrence Livermore Laboratory, the University of California at Berkeley and the Center for Astronomy and Space Sciences at the University of California San Diego where he worked on the BATSE experiment that was part of the Compton Gamma Ray Observatory (CGRO), launched in 1991. BATSE had as its main objective the study of cosmic gamma-ray bursts (GRBs) and made significant advances in this area of research. David became a world-renowned figure in the emerging field of GRB studies. He is best known for his widely-used analytic form of gamma-ray burst spectra known as the "Band Function". At a recent GRB conference in Huntsville Alabama, a young gamma-ray astronomer noticed his conference name tag and asked if he was really the person for whom the Band function is named. In fact David did much more, by providing important analysis of the GRB data which refuted previous claims for line features in their spectra and their distributions with respect to galaxies, which in part laid the foundation for their 1997 discovery as cosmologically distant objects.
After the CGRO mission ended, David moved to the Los Alamos National Laboratory where he worked mainly on classified research but continued to work on GRB energetics and spectra. When NASA planned two new follow-up missions to CGRO, the Swift and Fermi observatories, David seized an opportunity in 2001 to join the staff of the Fermi Science Support Center at the NASA Goddard Space Flight Center in Greenbelt Maryland. He was hired as the lead scientist for user support functions and to help to define and implement planning for the 2008 launch of the Fermi spacecraft. He brought a high level of energy and enthusiasm to the job, becoming in many ways the heart and soul of that organization. Neil Gehrels, the Goddard Astroparticle Physics Division Director and a Fermi deputy project scientist notes that "David was the perfect person for community support, with this outgoing personality and deep knowledge of astrophysics". David also became an important member of the Fermi science team; despite his failing health, he actively contributed to the first Fermi gamma-ray burst publication as well as making important contributions to the burst detection and data analysis techniques. He was also involved with planning the EXIST mission, a candidate for a future NASA mission. He will be greatly missed by his many friends and colleagues within the Fermi mission and the high-energy astrophysics community.
David is survived by his wife Debra, his sons Zvi and Gabriel, his brother Jonathan and his parents, Arnold and Ora. Contributions in David's memory may be made to Magen David Adom (link to http://www.afmda.org/ ) the American Cancer Society (link to http://www.cancer.org/docroot/home/index.asp ) , Beth Sholom Congregation and Talmud Torah in Potomac, Maryland (link to http://bethsholom.org/ ) , or the JSSA Home Hospice Association (link to http://www.jssa.org/services/senior/hospice ). A memorial service for David will be held at NASA/Goddard on July 10, 2009.

3. Congressional Visits Day - Julia Lee (Harvard) & Dieter Hartmann (Clemson)
The Science Engineering and Technology annual congressional visit took
place this year on April 28-29, in which the AAS took part with
several members of the HEAD executive committee in attendance. This
event came on the heels of the exciting April 27 speech given by
President Obama at the National Academy of Sciences promising renewed
commitment to science and technology. The two-day agenda for the
congressional visit itself was separated into a day-1 briefing at the
AAAS by Kei Koizumi (White House Office of Science and Technology
Policy), Michael Holland (Program Examiner for the Energy Branch
Office of Management and Budget), various staff members of the House
Science and Technology Committee (Louis Finkel and Dan Byers), and
Legislative Director Eric Werwa of the Office of Representative
Michael Honda (CA). Because the President's budget had not been
released, there was limited information that these speakers were able
to share. For the AAS and HEAD contingent, there were additional
briefings by Eileen Friel of the NSF and Jon Morse at NASA HQ. It
would seem that the NSF budget is healthy but does that translate to a
healthy astrophysics budget? NASA's is not, and it still awaits
confirmation of new leadership; the NSF is still in recruitment mode
for head of astrophysics. Day-2 consisted of a joint morning breakfast
accompanied by speeches from several senators, followed by individual
meetings with Senate and House staffers/representatives/senators from
one's constituent state, and for some of us more fortunate, a meeting
with Dr. Richard M. Obermann, staff director of the House subcommittee
on space and aeronautics of the Committee on Science and Technology, and
a true friend to our profession. For the most part, it was felt by most
that legislators and staff were eager to hear from the community.
Dry agenda details aside, some of the staffers were quite negative
about the importance of the NASA mission as evidenced by the quote
"NASA isn't sexy anymore", made in a day-1 briefing to a
large and diverse group. While it is encouraging that science has
regained a prominent role in the aspirations of the Nation and the
President's agenda, we have to ask ourselves, in light of the opinions
expressed by some staffers on this hill visit, whether NASA and
Astrophysics will even feature as a minor player in the collective
consciousness of the hill -- our opinion: at best, maybe. According
to these writers' perception, we seem to have fallen from the golden
heights of the post-Apollo years to the modern day cautionary tale.
So, while we still have friends on the hill, what message should we
take away from this surprisingly negative perception, despite the
overall positive message of the President's renewed interest in
science and technology? Was this negativity the opinion of a minority
of policy makers or is it something we should really start paying
attention to as a community? The answer may be somewhere in the
middle, with a strong slant towards the latter. While the new mantra
is appropriately focused on energy and the climate, we should take
care that astrophysics does not become dark (i.e. invisible) matter in
the thoughts of those who would control our collective financial
fate.
We thank Marcos Huerta (Bahcall Public Policy Fellow) and Kevin Marvel
(AAS Executive Officer) for arranging and organizing this important
opportunity. We strongly encourage the Astrophysics community to
appeal to the political leadership, at the state and national level,
with the positive message that astronomy and astrophysics engages
public (especially student) interest in science, has strong societal
impact, including e.g. the creation of high technology jobs, and is
therefore worthy of support and inclusion in the competitiveness and
recovery agendas. It is only too clear that more involvement, and
constant reminders are needed.

4. News from NASA Headquarters - Ilana Harrus
Report from NASA HQ
Astrophysics Division
A. RXTE keeps going
The President's fiscal year 2010 budget request for NASA's
Astrophysics Division proposes to continue operating the Rossi X-ray
Timing Explorer (RXTE) for another year. RXTE will proceed with
another cycle of investigations, including valuable complementary
observations to other missions such as the Fermi Gamma-ray Space
Telescope. Operations beyond FY 2010 will be subject to the
prioritizations of the 2010 Senior Review of operating missions.
B. President's budget announced
NASA released Thursday the $18.69 billion President's budget request
for fiscal year 2010. The budget request represents an increase of
$903.6 million, or 5 percent, above funding provided in the fiscal year
2009 Omnibus Appropriations Act. The Astrophysics Division of the
Science Mission Directorate (SMD) will receive a total of about $1.12
billion. This funding will allow continuation of major thrusts within the
Astrophysics Division, including development of JWST and Explorer
missions such as NuSTAR and ASTRO-H, operation of the existing suite
of Astrophysics observatories, and the Research and Analysis Program.
C. Research Opportunities in Space and Earth Sciences (ROSES)
A new edition of the ROSES NRA was released in February 2009. It
contains all of the information relevant to upcoming proposal
deadlines. Up-to-date information on proposal deadlines can be
accessed at: http://nspires.nasaprs.com/external/

5. HEAD in the News - Megan Watzke (w/input from Lynn Cominsky)
November 2008-April 2009
In the past six months, Chandra, Fermi, and Swift all continued to generate significant news coverage. The following stories helped keep high-energy astrophysics in the public eye during this period.
In December, NASA held a phone-based press conference to announce Chandra's latest contribution to the study of dark energy: http://www.chandra.harvard.edu/press/08_releases/press_121608.html
This led to articles in the New York Times, Washington Post, The Economist, and many other prominent outlets.
At the January AAS meeting in Long Beach, Fermi's discovery of a new class of gamma-ray only pulsar was featured in a press conference.
http://www.nasa.gov/mission_pages/GLAST/news/dozen_pulsars.html
Also in Long Beach, two complementary, but separate Chandra results on Cas A were released. These included the first-ever 3D flythrough of a supernova remnant and the dramatic changes in Cas A over Chandra's lifetime:
http://www.chandra.harvard.edu/photo/2009/casa/
http://www.chandra.harvard.edu/photo/2009/casa2/
In February, a Fermi discovery of the "most extreme" gamma-ray burst ever seen was announced:
B
http://www.nasa.gov/mission_pages/GLAST/news/high_grb.html
Also during this month, Chandra participated in the release of the Great Observatory image unveiling for the International Year of Astronomy (IYA). This composite image of M101 was distributed to dozens of museums and science centers around the country and created a lot of local news coverage:
http://www.chandra.harvard.edu/press/09_releases/press_021009.html
On April 3rd and 4th, Swift, Fermi, Hinode, and Chandra all participated in the "Around the World with 80 Telescopes" webcast, which was part of the "100 Hours of Astronomy" program for IYA. Interestingly, Chandra's released image for the webcast, PSR B1509-58, became a hit in the blogosphere because of the "hand-like" structure seen in the pulsar wind nebula:
http://www.chandra.harvard.edu/photo/2009/b1509/
This led to the story later getting picked up by CNN, msnbc.com, and other mainstream media.
A major newsmaker from Swift came at the end of April with the announcement of the most distant gamma-ray burst yet detected at a redshift of 8.2:
http://www.nasa.gov/mission_pages/swift/bursts/cosmic_record.html
This story was covered by NPR, the New York Times, and many other major outlets, helping to end this half-year of high-energy news with a bang.

6. Chandra X-ray Observatory Operations Report - Roger Brissenden (SAO) and
Martin Weisskopf (MSFC)
Chandra continued successful science operations during the last six months. In July the mission will reach the 10-year milestone, with mirror and instrument performance essentially unchanged from the first year of the mission. The symposium "Chandra's First Decade of Discovery" (Boston, 2009 September 22-25) will celebrate Chandra's science. Please register for the Science Symposium and the associated Calibration workshop at http://cxc.harvard.edu/symposium_2009/ .
Chandra experienced no anomalies during this period; all long-term subsystem trends continued as projected. The spacecraft passed through the winter eclipse season in December with expected power and thermal performance. Due to the mild and extended solar minimum, Chandra has suffered no radiation shut-down since 2006 December.
The Flight team uploaded 3 flight software patches to mitigate effects of long-term warming of the spacecraft. The first patch updated the on-board telescope secondary thermal database to treat a new contingency case associated with eclipses. The second enabled use of the HRC anti-coincidence shield as an auxiliary radiation monitor, in response to continued thermal degradation of the EPHIN radiation detector. The third modified a power-system parameter to avoid the eclipse flag from inadvertently toggling while the spacecraft is in sunlight. These steps will allow Chandra to continue operating safely and with high science efficiency.
The ACIS experienced a Front-End-Processor (FEP) reset, impacting one observation, attributed to a single-event upset (SEU) like those previously encountered. The CXC updated ACIS flight software to address a number of issues, such as avoiding Back-End Processor (BEP) telemetry-packet loss under certain timing conditions and precluding a BEP reset on FEP power-down.
Since November, Chandra's overall observing efficiency has remained close to optimal. During this period, the mission planning team responded to two fast-turnaround targets of opportunity. The science-data processing, archiving, and distribution proceeded smoothly, with time from observation to data release remaining at about a day. In March the CXC issued the first full release of the Chandra Source Catalog, available at
http://cxc.harvard.edu/csc/
The CXC received 668 Chandra Cycle-11 proposals by the March-17 deadline, plus 43 GTO proposals: This is a slight increase over Cycle 10. Cycle-11 observing time is over-subscribed by a factor of about five. The peer review will occur in Boston in June. Finally, the Chandra Press Office issued 10 press releases and 15 image releases since November. For a full listing, please see http://chandra.harvard.edu/press/ .
We look forward to seeing you at "Chandra's First Decade of Discovery" Symposium in September!
