Briefing: Galaxies

Tuesday afternoon's press conference, hosted by AAS Deputy Press Officer Inge Heyer, featured new findings on galaxies and galaxy clusters based on observations from radio waves through gamma rays. Reinout J. Van Weeren (Harvard-Smithsonian Center for Astrophysics) showed that colliding galaxy cluster MACS J0717 is effectively a giant particle accelerator. Harry I. Teplitz (Infrared Processing & Analysis Center/Caltech) extended the Hubble Ultra Deep Field into the ultraviolet. Roy E. Kilgard (Wesleyan University) profiled the population of black hole X-ray binaries in the Whirlpool Galaxy. And Marco Ajello (Clemson University) offered new insights into the cosmic evolution of Fermi BL Lacertae objects.
