ABSTRACT
Existing observations indicate most of the X-ray emission from the hot CGM or the corona of a galaxy can be attributed to stellar feedback, while the accretion induced hot halo gas, as predicted by galaxy formation models, is not detected. We propose an XMM-Newton survey of the M31 halo, in order to search for the accreted hot halo. We will study the spatial distribution of hot gas density, temperature, and metallicity. We will estimate the strength of collisional ionization to better model the UV absorption lines from the HST observed background AGN. These analyses will help us to explore if the accreted CGM is previously not detected because they have low density and distribute at large radii, or they have too low temperature to emit X-ray, or they have too low metallicity so X-ray emissivity.

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)
- CLASS 4: comments and suggestions from PI
