Radio properties of nearby groups of galaxies
  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. We report an age of ~18 Myr for the radio source 3C270 in NGC
4261 implying that the expansion was supersonic over a large fraction of its
lifetime. In NGC 1060 we detect a small-scale (20''/7.4 kpc) jet source with
the spectral index of $\alpha_{240}^{610}$=0.9 indicating a remnant of an old
outburst. Lastly in NGC 5982 the 610 and 235 MHz observations find a radio
point source in the central AGN with no evidence of jets or lobes and diffuse
emission from the disks (star formation).
