Description We propose to observe G1 (=Mayall II), the brightest and most massive globular cluster of M31. It is an extremely dense and massive globular cluster, an excellent target in which to search for a bright X-ray source. ROSAT did not observe it. The primary goal of our proposal is to determine whether G1 contains an X-ray source, as a pilot observation for a later proposal. If the source is bright we can make a preliminary spectral classification (neutron- star vs. black hole binary) and a preliminary search for orbital variation. It is interesting for theory to know whether this extremely dense cluster contains a bright source; and also which fractions of bright sources are neutron-star binaries and black-hole binaries.

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.
