  • The 18th Divisional Meeting has been Cancelled. The 18th Divisional meeting of the High Energy Astrophysics Division was scheduled to be held at the JW Marriott Tucson Starr Pass Resort & Spa.  However, due to the corona virus pandemic, this meeting was cancelled.  The HEAD Executive Committee considered holding the 18th meeting as a meeting-in-a-meeting at the 238th AAS meeting in June 2021 in Anchorage.  However, since the decision was made that the 238th meeting will be held online (because of the CoVID pandemic), the HEAD Executive Committee has decided not to participate in the virtual meeting.  Thus we made the decision to cancel the 18th Divisional meeting.  The next HEAD meeting is the 19th Divisional Meeting to be held (we hope) as an in-person meeting in Pittsburgh, in March 2022.
  • The HEAD Executive Committee is pleased to announce the following HEAD Award winners:  The 2021 Bruno Rossi Prize has been awarded to Francis Halzen and the IceCube Collaboration "for the discovery of a high-energy neutrino flux of astrophysical origin".  The 2021 Mid-Career Prize has been awarded to Anna Watts, "for her trailblazing work in the understanding of neutron star fluid dynamics, and developing and applying rigorous inference to obtain observational constraints on dense matter". The 2021 HEAD Dissertation Prize was awarded to Renee Ludlam for her dissertation entitled "A Hard Look at Accretion Around Neutron Stars". Her work showed how accretion disk reflection can be used to place limits on neutron star radii (and therefore the equation of state). The inaugural HEAD Innovation Prize was awarded to Dr. Richard Kelley "for his unflagging effort to make the transformational capabilities of the X-ray microcalorimeter available to the high energy astrophysics community". Congratulations to all the award winners. Please see the HEAD press release for more information.

  • 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.
