INTEGRAL U.S. Guest Observer Facility

The INTErnational Gamma-Ray Astrophysics Laboratory

INTEGRAL, was launched in October 2002 aboard a Russian Proton rocket,  and is providing a new insight into the most violent and exotic objects of the Universe,  such as neutron stars, active galactic nuclei and supernovae. INTEGRAL is also helping us to understand processes such as the formation of new chemical elements and the mysterious gamma-ray bursts, the most energetic phenomena in the Universe. Environments of extreme temperature and density, near the event-horizons of black holes, are a major topic of study with INTEGRAL.

These studies are possible thanks to INTEGRAL's combination of fine spectroscopy and imaging of gamma-ray emissions in the energy range of 15 keV to 10 MeV (using the SPI and IBIS instruments) and concurrent monitoring in the X-ray band (4-35 keV) using JEM-X, and in the optical (500-600 nm) band, using the OMC.

A project of the European Space Agency INTEGRAL, serves an international Guest Observer community. Participation by U.S. astronomers was supported by a Guest Observer Facility (GOF) at the NASA/Goddard Space Flight Center (GSFC) from the mission start until October 2010. Since then, the mirroring of the European INTEGRAL Public Data Archive into the HEASARC has been continued by the HEASARC.

  • First Announcement of 11th INTEGRAL Conference (18 Mar 2016)
    SRON Netherlands Institute for Space Research and the Astronomical Institute "Anton Pannekoek" of the University of Amsterdam are organizing the 11th INTEGRAL Conference: Gamma-Ray Astrophysics in Multi-Wavelength Perspective. It will be held 10-14 October 2016 in Amsterdam, The Netherlands.
  • INTEGRAL Observes Positron Annihilation during V404 Cygni Outburst (17 Mar 2016)
    A team led by scientists at the Max-Planck-Institut für extraterrestrische Physik (MPE) in Garching, Germany report the discovery of intense bursts of photons at energies near 511 keV, which they interpret as the signature of positron-electron annihilation near the microquasar V404 Cygni. The results have been published in the 17 March 2016 issue of Nature.

    INTEGRAL Public Data Archive Status
  • The HEASARC mirror to the INTEGRAL Public Data Archive now contains data through the June 10, 2016 public data release (revolution 1542). It also contains all data from recent observations for which the PI has allowed the data to be made public ealier than the 1 year proprietary period.

  • The next scheduled public data release is June 25, 2016.
