Scientific paper

The nearby spiral galaxy NGC 2841 is located in a direction of minimal Galactic foreground absorption and is exceptionally massive. A Chandra snapshot observation has already shown evidence for a large-scale diffuse X-ray-emitting halo around the galaxy. We propose a 30 ksec Chandra ACIS-S observation to determine the contribution from discrete X-ray sources and to resolve the X-ray structure in the galactic disk and bulge. This observation, complemented by our approved 40 ksec XMM-Newton exposure, will enable us to measure the content, morphology, thermal status, metallicity, and cooling rate of the diffuse hot gas. We will then quantitatively test galaxy formation theories, which predict substantial amounts of hot gas cooling around massive disk galaxies.
