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.

  • XMM-Newton AO-16 Results Released (02 Dec 2016)
    The list of XMM-Newton observing proposals accepted by the AO-16 Observing Time Allocation Committee is now available.
  • INTEGRAL IBIS 11-Year Hard X-Ray Survey Above 100 keV Source Catalog (29 Nov 2016)
    The all-sky catalog of 132 transient and persistent sources detected above 100 keV by INTEGRAL IBIS during 11 years of operations (INTEGRAL revolutions 26 to 1377) published in Krivonos et al. (2015, MNRAS, 448, 3766) is now available in Browse and Xamin.
  • Long-sought Signal Deepens Mystery of Fast Radio Bursts (FRBs) (21 Nov 2016)
    What causes split-second blasts of radio waves that appear in the sky from billions of light years away is one of the most perplexing mysteries in astronomy. Now, for the first time, astronomers using the Swift BAT have seen a flash of high-energy gamma-rays that looks as if it was emitted by the same event that produced an FRB on November 4, 2013. A paper by DeLaunay et al. on this event has just appeared in ApJ and is available online here .
  • Swift CALDB Data updated (21 Nov 2016)
    A new Swift clock correction file has been added to the Swift SC Caldb (CALDB update version 20161118)
  • NASA Space Telescopes Pinpoint Elusive Brown Dwarf (16 Nov 2016)
    In a first-of-its-kind collaboration, NASA's Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic object. This technique is useful for finding low-mass bodies orbiting stars, such as planets. In this case, the observations revealed a brown dwarf. This study by Shvartzvald et al. has just appeared in ApJ (2016, 831, 183).
  • Starvation Diet for Black Hole Dims Brilliant Galaxy (10 Nov 2016)
    Astronomers may have solved the mystery of the peculiarly volatile behavior of a supermassive black hole (SMBH) at the center of the active galaxy Mkn 1018. Combined data from Chandra and other observatories suggest that this SMBH is no longer being fed enough fuel to make its surroundings shine brightly. After discovering the AGN's fickle nature during a survey project using ESO's Very Large Telescope (VLT), astronomers observed it with both Chandra and Hubble. Other observatories used in this study include NuSTAR and Swift. Two papers on these results have just appeared in A&A: Husemann et al. and McElroy et al. .
