| Abstract | We propose a deep XMM-Newton observation of the nearest compact ellipticalgalaxy M32. The RGS will provide the first high-resolution spectrum of thecumulative soft X-ray emission of old stellar populations, with littlecontribution from low-mass X-ray binaries or diffuse hot gas. This spectraltemplate will be useful to the study of the average properties of thepopulations and, most importantly, will facilitate a reliable subtraction of thestellar contribution in the spectroscopic analysis of diffuse hot gas ingalactic spheroids in general. The EPIC spectrum will offer a complementary highsensitivity and broad energy coverage, badly needed for determining the natureof hard X-ray emission observed in the Galactic ridge and in nearby galaxies. |

| 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. |
