| Description | We are finally entering the era of studying the hot circumgalactic medium around nearby spiral galaxies observationally, in the wake of several recent detections out to 50 kpc. This hot gas records a galaxy.s history of feedback and accretion processes, and therefore it holds a number of important clues for understanding galaxy formation. Two especially important parameters are the metallicity of the gas and the density profile beyond 50 kpc, as these observables reveal the origin of the gas and constrain its total mass. Here we propose a follow-up observation of the giant spiral NGC 1961, in a mosaic pattern, in order to measure the metallicity of the CGM gas from 25-50 kpc, and its density profile from 50-100 kpc. |

| 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. |
