Ngc 2841, Xmm-Newton Proposal 02014401

Scientific paper

The nearby spiral galaxy NGC 2841 is located in a direction of minimal Galactic foreground absorption and is exceptionally massive, as evidenced by the disk rotation speed of 317 km/s. An 1.7 ksec Chandra snapshot observation has already shown evidence for a large-scale diffuse X-ray-emitting halo around the galaxy. We propose a 40 ksec XMM/Newton observation to measure the content, morphology, thermal status, metallicity, and cooling rate of the putative diffuse hot gas. We will then quantitatively test galaxy formation theories, which predict substantial amounts of diffuse X-ray emission from hot gas cooling around massive disk galaxies.
