The INTErnational Gamma-Ray Astrophysics Laboratory

INTEGRAL, launched in October 2002 aboard a Russian Proton rocket, 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 and concurrent monitoring in X-ray (4-35 keV) using JEM-X, and optical (500-600 nm) bands, using OMC.

A project of the European Space Agency INTEGRAL, serves an international Guest Observer community. Participation by U.S. astronomers is supported by a Guest Observer Facility (GOF) at the NASA/Goddard Space Flight Center (GSFC).

7th INTEGRAL Announcement of Opportunity (13 Jan 2009)
ESA has released the 7th Announcement of Opportunity for observing proposals with INTEGRAL. The deadline for proposals is February 20, 2009. Additional information can be found on the ESA INTEGRAL website and on the "Proposals and Tools" page of the INTEGRAL US GOF.

Extension of INTEGRAL AO-6 (19 Nov 2008)
It has been decided to extend the duration of the ongoing AO-6 cycle by two months, until 16 October 2009. The duration of AO-7 will be extended by 2.5 months, it will therefore last from October 2009 until end of December 2010. Subsequent AO's are expected to be annual again.

Happy Birthday INTEGRAL! (17 Oct 2008)
INTEGRAL is celebrating six successful years in space today! Instruments and spacecraft are continuing to perform well and the scientific output keeps the community busy as recent workshops in Copenhagen and Rome demonstrate. We are all looking forward to more years of discoveries and interesting results.
