| Description | In galaxy clusters, cooling from the intra-cluster medium provides the cold gas which fuels the central AGN and thus maintains thermal balance. We also see evidence of such cooling in massive, X-ray luminous groups. However, some lower luminosity groups have central galaxies which are actually richer in cold gas, despite their lack of cool cores or active radio jets. We propose to observe two such systems, with the goal of determining the properties and dynamical state of the intra-group medium, measuring their cooling rate, and searching for evidence of old AGN outbursts. Moderate exposures will provide order of magnitude increases in depth over the available observations for these groups, giving us new insight into the origin of their cold gas reservoirs. |

| 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. |
