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 not only data obtained by high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, but also data from space missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB).

Try ROSAT 3c273 1d to get ROSAT data within one degree of 3c273 or chanmaster bii>80 status='archived' to get archived Chandra Observations data near the north galactic pole.

Note: For more than one target or when using any qualifier other than a mission , use quotes around targets that have embedded white space.(e.g., 'ar lac').

  • Suzaku Cycle 10 Target List Available (21 Apr 2015)
    The list of accepted Suzaku AO-10 targets is now available.
  • Mysterious 'Cold Spot': Fingerprint of Largest Structure in the Universe? (20 Apr 2015)
    Szapudi et al. (2015, MNRAS, 450, 288) have used the WISE-2MASS IR galaxy catalogue matched with Pan-STARRS1 (PS1) galaxies to search for a supervoid in the direction of the cosmic microwave background (CMB) cold spot. Their results are indeed consistent with such a supervoid as a plausible cause for the WMAP/Planck cold spot
  • Fermi LAT High-Energy (1FHL) Source Catalog (17 Apr 2015)
    This catalog of 514 gamma-ray sources detected at energies above 10 GeV by the Fermi Large Area Telescope in its first 3 years of operations (taken from Ackermann et al. 2013, ApJS, 209, 34) is now available in Browse and Xamin.
  • Swift Data Reprocessing (17 Apr 2015)
    The Swift Data Center is now reprocessing the Swift data for the entire mission in chronological order using the current version of the Swift Data Center pipeline (v. 3.16.08). All the data for 2005 have been reprocessed and delivered to the HEASARC. The archives in Italy and UK are currently populating their archives with the new data. Currently the reprocessing rate is about 3 months per month.
  • Astronomers discover two classes of Type Ia Supernovae (14 Apr 2015)
    Milne et al. 2015, ApJ, 803, 20 have found that type Ia supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before. The data collected with Swift were crucial because the differences between the populations are subtle in visible light, but became obvious only through Swift's dedicated follow-up observations in the ultraviolet with UVOT.
