Abstract | GT-We will make long observations of the core of M31, and of two fields alongthe major axis to the south, in order to study its X-ray source populations, inparticular the X-ray binary content of the galaxy. The observations will providea census of a large fraction of the binary population. The XMM data will allow avariety of issues to be addressed, including, e.g., the star formation historyof M31. The factor >10 increase in sensitivity compared to the ROSATobservations, coupled with hard band coverage, will produce superb data for asignificant fraction of the already known M31 sources. |

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. |
