| Abstract | Outbursts of SMBHs have significant impact on structure formation and evolution.Their imprint on ICM (cavities, shocks and ^ated entropy) provides anhistorical chronicle of the SMBH activity. However, AGN heating has not beenwell studied in groups (especially for groups hosting strong radio AGN),although it should affect the group gas much more than the cluster gas. Wepropose XMM observations of two groups with strong radio AGN. Both have clearfeatures indicative of heating from the radio AGN in short XMM or Chandraexposures. The results will fill the little explored regime of the L_radio -L_power plane for groups. One galaxy also has a mysterious emission line in thespectrum of its AGN, which needs to be tested and studied with deeper data. |

| 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. |
