| Description | We propose a 22.5 arcmin offset observation of the unique galaxy group NGC 5044 to obtain unprecedented constraints on star formation history and evolution in groups of galaxies. Having already analyzed the inner 100 kpc of this system in a modest pointed AO1 observation, we will now investigate the critical transition region (100-600kpc) where metal abundances have not been previously studied. First, we will definitively measure the total Fe mass in this system to a large fraction (0.6) of the virial radius. In addition, we expect to measure a sharp drop in abundance as we explore the ICM untouched by SN from the dominant galaxy. This directly constrains both the IMF and the uncertain SNII Fe yield. |

| 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. |
