HEAD History Items


  • HEAD election results are in. Dr. Fiona Harrison has been elected to a 2-year term as HEAD Vice Chair, and Dr. Gabriela Gonzalez and Dr. Laura Brenneman have been elected as members of the HEAD Executive Committee, replacing Dr. Elizabeth Hays and Dr. Colleen Wilson=Hodge.  We thank Dr. Hays and Wilson-Hodge for their service to the Division.  Dr. Robert Petre is the new HEAD Chair, while Dr. Chris Reynolds is now HEAD Past Chair.  We also thank outgoing HEAD Past Chair Nick White for his six years of service to the HEAD, as Vice Chair, Chair and Past Chair.
  • We are saddened to note the passing of Dr. Jeffrey McClintock on Nov 8th, 2017. Dr. McClintock worked at the Center for Astrophysics and was a prime authority on X-ray studies of stellar mass black holes. Dr. McClintock was awarded the 2009 Bruno Rossi Prize along with Charles Bailyn and Ron Remillard for the measurement of the masses of Galactic black holes.  Dr. McClintock also served on the HEAD Executive Council from 1985-1986.
  • NASA has established a study office and study team for LISA, the Laser Interferometer Space Antenna.  LISA is a space-based gravitational wave observatory, and was selected by ESA in June 2017 as the 3rd Large mission in the Cosmic Visions Programme.
  • Gravitational and electromagnetic radiation has been detected from a neutron star merger event, GW170817 = GRB170817A.
  • Rainer Weiss, Barry C. Barish and Kip S. Thorne have won the 2017 Nobel Prize in physics “for decisive contributions to the LIGO detector and the observation of gravitational waves”.
  • NASA has selected six astrophysics Explorers Program proposals for concept studies (3 Medium Class missions and 3 Missions of Opportunity). Arcus, a high energy resolution X-ray observatory was one of the three accepted Medium Class mission proposals.  The Accepted Missions of Opporunity proposals include COSI-X, a balloon-borne experiment to survey the gamma-ray sky at 0.2-5 MeV and ISS-TAO, a wide-field X-ray transient detector to be berthed on the International Space Station.
  • NASA is funding a number of Probe-class mission concept studies to be concluded by early 2019 for inclusion in the 2020 Decadal Survey.  These include the following missions: TAP, the Transient Astrophysics Probe (PI Jordan Camp); the Inflation Probe (PI S. Hanany); AXIS, a high spatial resolution X-ray imager (PI Richard Mushotzky); POEMMA, a multi-messenger astrophysics mission (PI Angela Olinto); and STROBE-X, an X-ray timing experiment (PI Paul Ray). 
  • Dr. Mike Juda was posthumously awarded the NASA Exceptional Public Service Medal for his "critical contributions to the effective operation and outstanding scientific productivity of the Chandra X-ray Observatory."
  • Dr. Morgan Macleod and Dr. Eric Coughlin are recipients of the International Astronomical Union's PhD prize. Dr. Coughlin (UC Berkeley) won the Division D award for his dissertation "The Evolutionary Pathways of Tidal Disruption Events: from Stars to Debris Streams, Accretion Disks, and Relativistic Jets".  Dr. Morgan Macleod (UC Santa Cruz) won the Division G prize for his dissertation "Social Stars: Modeling the Interactive Lives of Stars in Dense Clusters and Binary Systems in the Era of Time Domain Astronomy".
  • China launched the Hard X-ray Modulation Telescope (HXMT) on June 15 at 03:00 UT  from the 603 Launch Pad of the LC43 Launch Complex. The new orbiting telescope will be used to monitor pulsars and other objects that could help unravel the mystery of their energy sources.  Congratulations to the HXMT team.
  • The Neutron Star Interior Composition Explorer (NICER) X-ray timing observatory was launched as part of the Commercial Resupply Services-11 (CRS-11) mission aboard a SpaceX Falcon 9 rocket on June 3, 17:07 EDT (21:07 UTC). The Dragon capsule has arrived and has berthed with the ISS, and NICER has now been extracted from the Dragon trunk and has been installed onto the Space Station's ExPRESS Logistics Carrier (ELC 2) Site 7, and is currently being powered up. Please see the NICER Latest News page for updates. Congratulations to the entire NICER team!
  • The 2017 HEAD Dissertation Prize is awarded to Dr. Eric Coughlin for his thesis entitled "The Evolutionary Pathways of Tidal Disruption Events: From Stars to Debris Streams, Accretion Disks, and Relativistic Jets". This work has significantly advanced the standard theory of relativistic hydrodynamics and has yielded substantial new results detailing the physical phenomena which occurs when a star falls into a supermassive black hole. This thesis explores all phases of this process, from the initial disruption of the star, through the formation of an accretion flow onto the black hole, to the eventual acceleration of a relativistic jet, and provides an essential framework for a developing field of high energy astrophysics.

  • The 2017 HEAD Mid-Career Prize has been awarded to Prof. Jon Miller (U. Michigan) for his seminal high resolution X-ray observations of accreting black hole systems. His work has fundamentally advanced our understanding of accretion disk winds and the dynamics of the in-falling material produced by the tidal disruption of a star by a black hole. As the Mid-Career Prize winner, Prof. Miller will give a plenary talk at the Sun Valley HEAD meeting on this topic preceded by a short prize ceremony. Please see the press release for more information.
  • The 2017 David N. Schramm Award for high-energy astrophysics science journalism has been awarded to Nadia Drake for her article entitled "Found! Gravitational Waves, or a Wrinkle in Spacetime", published on the National Geographic's website on February 11, 2016. Please see the press release issued on April 17, 2017 for more information.
  • Dr. Neil Gehrels has been named as a Dan David Prize Laureate for 2017. The award statement reads "For being the principal investigator of NASA's Swift Gamma Ray Burst Mission, which has transformed our view of the transient and variable sky in gamma-rays and in X-rays. Under his leadership, Swift has discovered over 1000 of the enigmatic and extreme cosmic explosions called gamma-ray bursts, and has revealed their properties, distances, and environments, well beyond what was previously known, with profound implications for their understanding. It was with great sorrow that we heard of the passing of Prof. Gehrels. The Dan David Prize joins the Astronomy world in mourning. It is an honor to include him in the Dan David Prize Community of laureates." Dr. Gehrels shares the 2017 prize with Prof. Shri Kulkarni and Prof. Andrzej Udalski.
  • NASA has selected the Imaging X-ray Polarimetry Explorer (IXPE) mission as the latest Explorer mission. IXPE will fly three space telescopes with cameras capable of measuring the polarization of these cosmic X-rays. Dr. Martin Weisskopf of NASA’s Marshall Space Flight Center will lead the mission as Principal Investigator, while Ball Aerospace in Broomfield, Colorado will provide the spacecraft and mission integration, and the Italian Space Agency will contribute the polarization sensitive X-ray detectors. Congratulations to Dr. Weisskopf and the entire IXPE team.
  • Dr. Gabriela González and the LIGO Scientific Collaboration have been awarded the 2017 Bruno Rossi Prize "for the first direct detections of gravitational waves, for the discovery of merging black hole binaries, and for beginning the new era of gravitational-wave astronomy." Please see the press release for more information.
  • Dr. Victoria Kaspi (McGill) was appointed to the Order of Canada. The Order of Canada was created in 1967 and is one of  Canada's highest civilian honors and recognizes outstanding achievement, dedication to the community and service to the nation.
  • Dr. Gabriela González (LSU) was named one of Nature's 10, "Ten people who mattered this year".
  • Neil Cornish (Montana State) and Kristin Madsen (Caltech) are the new HEAD executive committee members, replacing Daniel Wang and Mark Bautz, whose terms are ending. We'd like to thank both Daniel and Mark for their valued service to the HEA community as executive committee members over the past three years, and welcome Kristin and Neil.
