| Abstract | We propose to search for X-ray pulsations from four of the hard X-ray IGRsources that have been discovered by the INTEGRAL satellite. Our targets are inthe Norma region of the Galaxy and are candidate neutron star High-Mass X-RayBinaries. The sources are persistent in X-rays as evidenced by strong detectionsof all four during brief (~5 ks) Chandra observations that occurred during 2005April-July. The proposed observations are critical to definitively identifythese sources as neutron star X-ray binaries. These studies are important forcharacterizing the population of IGR sources, leading to a better understandingof binary evolution and compact object formation. |

| 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. |
