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.

The HEASARC is a member of the NASA Astronomical Virtual Observatories (NAVO) where we work with other NASA archives to ensure comprehensive and consistent VO access to NASA mission datasets. Users may now query the HEASARC's catalogs using VO-enabled services and specialized tools. This page describes how to get to the HEASARC VO-enabled services and provides information on other HEASARC VO activities.

  • IRAM NOrthern Extended Millimeter Array (NOEMA) Observation Log (20 Nov 2017)
    The second version of the IRAM NOEMA - the successor to the Plateau de Bure Interferometer (PdBI) - observing log (Dan et al. 1991-2017, IRAM Newsletters) containing 1,231 observations from May 31, 2015 through September 29, 2016 is now available in Browse and Xamin, as well as an updated version of the IRAM PDBI observing log.
  • Sixth Announced Gravitational Wave Detection, GW 170608 (16 Nov 2017)
    The LIGO Scientific and Virgo collaborations report the detection of yet another gravitational wave signal, dubbed GW 170608, emitted during the final moments of the merger of two black holes with masses of about 7 and 12 times the mass of the sun located at a redshift of ~0.07 (340 Mpc). This is one of the first cases where black holes detected through gravitational waves have masses similar to those detected indirectly via e-m radiation, such as X-rays The discovery paper was just submitted to ApJL.
  • Swift CALDB Data updated (15 Nov 2017)
    The Swift XRT Caldb has been updated (CALDB update version 20171113).
