INTEGRAL observation of X‐ray Binaries

This paper shortly reviews a number of significant results recently obtained with data from Galactic Gamma‐Ray Binaries with the INTEGRAL/IBIS Gamma‐ray Imager on‐board INTEGRAL. The Observatory, three and half year after the launch has an unprecedented data base of gamma ray observations covering to a large extent the Galaxy plane and with lower exposure a substantial part of the extragalactic sky. The ESA policy for INTEGRAL is to make publicly available all the data collected after one year of proprietary rights, ensuring at this stage of the mission a valuable data base to the scientific community at large. The IBIS high sensitivity and capability to provide at the same time image, spectra and time profiles of all the sources in the wide field of view (∼1000 squared degree) guarantee a powerful tool to deeply observe the Galactic Centre and exploit class oriented studies of the high energy population. Recently the IBIS survey has been uptated and more than 400 sources have been detected in the 20–100 ...
