We propose a 100 ksec observation of NGC 4472 to study the globular cluster(GC)-X-ray binary connection over a large field of view. These data will beespecially useful for comparing the X-ray properties of metal rich and metalpoor globular clusters and for comparing the spatial profiles of cluster andnon-cluster sources. Wide field data are key because metal poor clusters arerare in the inner regions of galaxies and because different spatial profiles arepredicted depending on whether non-GC XRBs are formed in the field or in GCs andthen ejected. The broadband spectroscopy will allow testing of stellar windmodels for the spectral differences as a function of metallicity. We will alsosearch for eclipses to measure orbital periods.

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.
