| Description | We propose to continue our XMM-Newton program to search for X-ray pulsations from hard X-ray INTEGRAL (IGR) sources. Over the past few years, INTEGRAL has found a surprising number of High-Mass X-ray Binaries (HMXBs), and the large number of new supergiant HMXBs is providing information that is important to our understanding of HMXB evolution. As many of the IGR HMXBs have extreme properties such as high column densities and rapid X-ray flares, we are still in the process of understanding where they fit in relative to previously known HMXBs. Detection of pulsations is important for establishing the presence of a neutron star, determining the distribution of spin periods, and for providing an opportunity to determine binary parameters, including the neutron star mass. |

| 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. |
