Abstract
We propose a deep XMM-Newton observation of the nearest compact elliptical galaxy M32. The RGS will provide the first high-resolution spectrum of the cumulative soft X-ray emission of old stellar populations, with little contribution from low-mass X-ray binaries or diffuse hot gas. This spectral template will be useful to the study of the average properties of the populations and, most importantly, will facilitate a reliable subtraction of the stellar contribution in the spectroscopic analysis of diffuse hot gas in galactic spheroids in general. The EPIC spectrum will offer a complementary high sensitivity and broad energy coverage, badly needed for determining the nature of hard X-ray emission observed in the Galactic ridge and in nearby galaxies.
Papers
Authors marked in red are (co-)investigators in the proposal
Classification of papers are:
- CLASS 1:
papers that present specific XMM-Newton observations
- CLASS 2:
papers that refer to published XMM-Newton results with
complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3:
further deliveries which resulted from the program and which are made
available to the community (e.g. source catalogues, processed images or
spectra in public data base)
