Cosmic-ray-driven outflows have been suggested to play an essential role ingalaxy formation and evolution. But their relations to galactic coronae andenvironments remain unknown. We propose a deep XMM-Newton observation of theisolated edge-on Sc galaxy NGC 3044, which shows an extended radio halo poweredby galaxy-wide star-forming activity. This observation will enable us to measurethe density structure, as well as the overall extent, morphology,thermal/chemical states of the corona. We will then examine the interplaybetween the corona and cosmic-ray outflows from the galactic disk. The resultswill be compared with those from existing studies of similar galaxies, butmostly undergoing with strong tidal interactions with companions, to explore environmental effects.

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.
