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.

Latest INTEGRAL News

  • INTEGRAL AO-16 General Program Approved (27 Jun 2018)
    The INTEGRAL AO-16 General Program, as recommended by the Time Allocation Committee (TAC) and approved by ESA's Director of Science (Prof. Gunther Hasinger), has been released and the observers have been informed.
  • 16th INTEGRAL Announcement of Opportunity (06 Mar 2018)
    ESA invites you to submit proposals to the International Gamma-ray Astrophysics Laboratory (INTEGRAL) 16th "Announcement of Opportunity" (AO-16) call for proposals, for observations to be performed during 2019. As previously, ESA also provides the opportunity to propose for coordinated observations with XMM-Newton, NuSTAR, and/or Swift with a total of 300 ks, 100 ks, and 150 ks, respectively, of their available time. Documentation, proposal submission and support software for this Announcement are being made available via the ESA INTEGRAL website. The deadline for proposal submission is Friday, April 13, 2018, 14:00 CEST.
  • INTEGRAL Mission Extended Through 2019 (18 Dec 2017)
    The ESA Science Programme Committee (SPC) has approved extending the INTEGRAL mission by one year through 31 December 2019. A proposal to extend INTEGRAL through 2020 will be presented at the next meeting of the SPC in February 2018.

    INTEGRAL Public Data Archive Status
  • The HEASARC mirror to the INTEGRAL Public Data Archive now contains data through the August 10, 2018 public data release (revolution 1836). It also contains all data from recent observations for which the PI has allowed the data to be made public earlier than the 1 year proprietary period.

  • The next scheduled public data release is August 10, 2018.
