The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA's (and other space agencies') missions studying electromagnetic radiation from extremely energetic cosmic phenomena ranging from black holes to the Big Bang. Since its merger with the Legacy Archive for Microwave Background Data Analysis (LAMBDA) in 2008, the HEASARC archive contains data obtained by high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from space missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB) radiation in the sub-mm, mm and cm bands.

  • A Black Hole Story Told by a Cosmic Blob and Bubble: The Mystery of Hanny's Voorwerp (10 Aug 2016)
    Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy. Using data from the Chandra X-ray Observatory and other telescopes, Lia Sartori and colleagues are piecing together clues from a cosmic 'green blob' (dubbed Hanny's Voorwerp) and a gas bubble in the nearby galaxy IC 2497 that could be a new way to probe the past activity of a giant black hole and its effect on its host galaxy. A paper on these results recently appeared in MNRAS and is available online here.
  • Xamin update August 2016 (08 Aug 2016)
    For this Xamin update we have reinstated the Product Explorer for Grid queries and added bibliography table options. The Product Explorer allows users to see and select the kinds of products associated with query results displayed as a grid. Look … Continue reading
