Title The Interaction of Hot and Cold Gas Within Galaxies


DOI 10.5270/esa-nw3nh7a
Author Dr Jimmy Irwin
Description Sa galaxies have roughly equal amounts of hot and cold gas, yet little is known about the interaction between the two phases. It is possible that the gas is thermally coupled, with cold gas cooling hot gas where the two phases interface. This would lead to a softening of the X-ray spectrum in the area of overlap. Alternatively, the phases could be thermally isolated, so that the cold gas in front of the hot gas absorbs soft X-rays behind it. We propose to observe the Sa galaxy IC~5267, which has an unusual HI distribution to search for the interaction between the two phases of its interstellar medium.

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.
