Outbursts of super-massive black holes openParSMBHsclosePar have a significant impact on structure formation and evolution. However comma AGN heating from SMBHs has not been well studied in galaxy groups. The main reason is that groups are X-ray faint around the center comma especially for those hosting strong radio AGN. We propose XMM observations of two nearby galaxy groups 3C 66B and IC 2476 comma both of which host strong radio AGN comma to study AGN feedback in groups. XMM.s high sensitivity at soft X-ray band makes it the best instrument for this project. The results will fill the little-explored regime of the L_keyOpen radiokeyClose - L_keyOpen powerkeyClose plane for galaxy groups and improve our understanding of AGN heating in groups.
