| Description | 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. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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. |
