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').

  • NuSTAR Cycle 1 Results (03 Mar 2015)
    The list of NuSTAR targets accepted by the Cycle 1 peer review is now available, Cycle 1 observations will start to be routinely performed on April 1, 2015. Written evaluations will be sent to all NuSTAR Cycle 1 PIs in the next few weeks. As specified in the AO, U.S. PIs of proposals with category A or B targets will be invited to submit phase-2 funding proposals. Note that 0.5 Ms of NuSTAR observing time is also available through the Chandra Cycle 17 CfP, due March 17.
  • Chandra CALDB 4.6.7 installed at the HEASARC (26 Feb 2015)
    CalDB 4.6.7 is now installed and available at the HEASARC. Chandra 4.6.7 was released on February 23, 2015. Note that this release requires CIAO 4.3 or higher...
  • An Intriguing New Member of the Black Hole Family Tree (26 Feb 2015)
    A newly discovered cosmic object may help provide answers to some long-standing questions about how black holes evolve and influence their surroundings, according to Mezcua et al. (2015, MNRAS, in press), who observed it with Chandra and the European VLBI Network. This intriguing object, called NGC2276-3c, is located in an arm of the spiral galaxy NGC 2276. With an inferred mass of 50,000 solar masses, it appears to be an 'intermediate-mass black hole' or IMBH.
  • NASA, ESA Telescopes Give Shape to Furious Black Hole Winds (19 Feb 2015)
    Five simultaneous observations by Nuclear Spectroscopic Telescope Array (NuSTAR) and the XMM-Newton observatory are showing that fierce winds from a supermassive black hole in PDS 456 blow outward in all directions -- a phenomenon that had been suspected, but difficult to prove until now. See Nardini et al. (2015, Science, 346, 860) for the full details.
  • The Million Quasars Catalog (19 Feb 2015)
    The latest version (v4.4, 6 February 2015) of the MILLIQUAS Catalog (Eric Flesch 2009 - 2015) containing more than one million (1,151,011 to be exact) likely quasars is now available in Browse and Xamin.
