We are finally entering the era of studying the hot circumgalactic medium aroundnearby spiral galaxies observationally, in the wake of several recent detectionsout to 50 kpc. This hot gas records a galaxy.s history of feedback and accretionprocesses, and therefore it holds a number of important clues for understandinggalaxy formation. Two especially important parameters are the metallicity of thegas and the density profile beyond 50 kpc, as these observables reveal theorigin of the gas and constrain its total mass. Here we propose a follow-upobservation of the giant spiral NGC 1961, in a mosaic pattern, in order tomeasure the metallicity of the CGM gas from 25-50 kpc, and its density profilefrom 50-100 kpc.

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.
