Title Constraining the Wind Origin in NGC 3079 through X-ray Temperature

Description The impact of galactic superwinds on their galaxies and the intergalactic medium depends on the driving mechanism, which is controversial. Two leading candidates are thermally driven and cosmic ray-driven winds, which predict different velocity profiles. This will be reflected in the temperature of the soft X-ray emitting gas. Specifically, one can determine whether a wind is accelerating or decelerating through a temperature gradient, since the soft X-rays come from shock-heated material. Here we propose searching for this gradient around NGC 3079, a nearby, edge-on superwind galaxy where soft X-rays are detected to a height of 20-25 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.
