Abstract The nearby spiral galaxy NGC 2841 is located in a direction of minimal Galacticforeground absorption and is exceptionally massive, as evidenced by the diskrotation speed of 317 km/s. An 1.7 ksec Chandra snapshot observation has alreadyshown 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 predictsubstantial amounts of diffuse X-ray emission from hot gas cooling aroundmassive disk galaxies.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
