Outbursts of super-massive black holes (SMBHs) have a significant impact onstructure formation and evolution. However, AGN heating from SMBHs has not beenwell studied in galaxy groups. The main reason is that groups are X-ray faintaround the center, especially for those hosting strong radio AGN. We propose XMMobservations of two nearby galaxy groups 3C 66B and IC 2476, both of which hoststrong radio AGN, to study AGN feedback in groups. XMM.s high sensitivity atsoft X-ray band makes it the best instrument for this project. The results willfill the little-explored regime of the L_{radio} - L_{power} plane forgalaxy groups and improve our understanding of AGN heating in groups.

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.
