| Description | To date more than 40 new bright hard X-ray Galactic plane sources have been discovered with INTEGRAL, and 10 of them have follow-up observations with XMM-Newton or Chandra. In most cases, the X-ray data exhibit slow pulsations, and the absorbing column density appear much larger than expected in the Galaxy or in front of the companion star. Many of those sources are persistent and seem to belong to a new class of HMXB, with a slow pulsar orbiting in a dense circumstellar material or within the companion stellar envelope itself. The goal of this proposal is twofold. We propose (1) to observe several additional persistent new INTEGRAL sources and (2) to study more in depth a few already studied sources. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
