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.

    INTEGRAL Public Data Archive Status
    The HEASARC mirror to the INTEGRAL Public Data Archive now contains data through the April 10, 2014 public data release (Rev 1272).

    The HEASARC archive also contains the first set of INTEGRAL public data (through Rev 1392) from the ToO observations of SN2014J. Additional data will be added when available.

  • The next scheduled public data release is April 25, 2014.
