Abstract 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 XMM-Newton, which allowed us to findcounterparts in the soft x-rays 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 XMM-Newton to measure their x-ray 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.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
