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) radiation in the sub-mm, mm and cm bands.

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').

  • Physics of the Cosmos (PCOS) Newsletter (03 Aug 2015)
    The PCOS Program Office is pleased to announce that the August 2015 PCOS Newsletter is now available, including updates on LISA Pathfinder (LPF), Athena and Euclid, and a message from Paul Hertz, the Director of NASA's Astrophysics Division.
  • NASA Selects Proposals to Study Neutron Stars, Black Holes and More (31 Jul 2015)
    NASA has selected five proposals submitted to its Explorers Program to conduct focused scientific investigations and develop instruments that fill the scientific gaps between the agency's larger missions. The selected proposals, three Astrophysics Small Explorer missions (PRAXyS, IXPE and SPHEREX) and two Explorer Missions of Opportunity, will study polarized X-ray emissions from neutron star-black hole binary systems, the exponential expansion of space in the early universe, galaxies in the early universe, and star formation in our Milky Way galaxy.
  • HEASoft 6.17, XSPEC 12.9.0 released (30 Jul 2015)
    Released July 29, 2015; primarily driven by updates to the NuSTAR and Swift/XRT software, but also includes updates to other packages which have been revised to mirror the current development versions in use at the HEASARC. XSPEC version 12.9.0 also released as part of HEASoft 6.17....
  • VLA Gould's Belt Survey Taurus-Auriga Complex Source Catalog (29 Jul 2015)
    This catalog listing the radio properties and counterpart information for 610 sources detected by the JVLA at 4.5 and/or 7.5 GHz in large-scale (127 different target fields), deep (~18-25 microJy) observations of the Taurus-Auriga complex (from Dzib et al. 2015, ApJ, 801, 91) is now available in Browse and Xamin.
  • Pulsar Punches Hole In Stellar Disk (28 Jul 2015)
    The double star system PSR B1259-63/LS 2883 contains a star about 30 times as massive as the Sun and a pulsar. According to Pavlov et al. (2015, ApJ, 806, 192) the fast-moving pulsar in this binary appears to have punched a hole in a disk of gas around its companion star and launched a fragment of the disk outward at an average speed of 7 per cent of the speed of light. Chandra is tracking this cosmic clump, which appears to be picking up speed as it moves out.
