Radio properties of nearby groups of galaxies

Understand

Much of the evolution of galaxies takes place in groups where feedback has the greatest impact on galaxy formation.

• By using an optically selected, statistically complete sample of 53 nearby groups (CLoGS), observed in Radio (GMRT) and in X-rays (Chandra and XMM-Newton), we aim to characterize the radio-AGN population in groups and examine their impact on the intra-group gas and member galaxies.
• The sensitivity to older electron populations at 240 MHz and the resolution of 610 MHz is the key to identify past and current AGN activity.
• Here we will present first results from three different galaxy groups analysed so far.
