SEARCHING FOR THE COUNTERPARTS OF NEW INTEGRAL SOURCES

INTEGRAL has recently completed its first Galactic Centre Deep Exposure (GCDE).A handful of new bright (50 mCrab) sources have been discovered above 15 keV.Some of them have been observed by XMMNewton, which allowed us to findcounterparts in the soft xrays and then in the optical. In addition, INTEGRALdetected a number of new gamma ray sources at a level of 5 mCrab. We propose toobserve some of them with XMMNewton to measure their xray spectrum and theirposition with an accuracy that will allow follow up studies in the infrared /radio bands. Such studies are essential to determine the nature of the newsources. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
