ABSTRACT
The hot halos of spiral galaxies contain material accreted from the intergalactic medium and material expelled from the disk. The mass in each component constrains galaxy formation models, and can be distinguished by the metallicity. However, isolating the hot gas and measuring its metallicity requires a large number of photons, and halos tend to be faint. The best candidate is NGC 891, a nearby, edge-on Milky Way analog with an X-ray bright halo. Existing data indicate an accretion rate of 0.2 Msun/yr, but there are too few photons to rule out several other plausible halo models. We will measure the accretion rate and the hot gas composition up to 8 kpc from the disk.

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
