| Abstract | The impact of galactic superwinds on their galaxies and the intergalactic mediumdepends on the driving mechanism, which is controversial. Two leading candidatesare thermally driven and cosmic ray-driven winds, which predict differentvelocity profiles. This will be reflected in the temperature of the soft X-rayemitting gas. Specifically, one can determine whether a wind is accelerating ordecelerating through a temperature gradient, since the soft X-rays come fromshock-heated material. Here we propose searching for this gradient around NGC3079, a nearby, edge-on superwind galaxy where soft X-rays are detected to aheight of 20-25 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. |
