| Description | We have analyzed archived Chandra data for a sample of 18 low-luminosity early-type galaxies and found that all of the galaxies are gas poor. The ratio of gas mass to stellar mass in these galaxies is ten times less than that found among more luminous galaxies, suggesting the presence of galactic winds in these systems.We find that Type Ia supernovae are energetically favored over AGN as the dominant heating mechanism driving the winds. If these galaxies possess SNeIa driven galactic winds, then the Fe abundance of the hot gas should be highly super solar. |

| 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. |
