Author Prof Anthony Dean
Description Of the 200+ galactic sources observed by INTEGRAL a consistent fraction of the point sources have not been associated with previously indentified objects. Follow up studies have identified that a significant number of these sources are highly obscured, HMXBs with a neutron star companion. Understanding the detailed mechanics of these systems and their place in the general picture of binary star evolution are the dual objectives of this proposal. We request observing time to exploit the powerful spectroscopic, imaging and timing capabilitie of XMM to find counterparts for 7 unidentified, persistent INTEGRAL sources discovered by the IBIS-ISGRI instrument, which are clustered in the Crux spiral arm tangent and are HMXB candidates. Thus identify the nature of the underlying system.

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.
