NGC741 - Mergers and AGN feedback on galaxy group scale

Low mass systems play an essential role in upcoming cosmological studies like eROSITA. Though the effects of AGNs and merging processes are of special importance to quantify biases like selection effects or deviations from hydrostatic equilibrium, they are poorly understood on the galaxy group scale. We present an analysis of recent deep Chandra and XMM observations of NGC 741, which provides an excellent example of a group with multiple concurrent phenomena: an old central radio galaxy, a spectacular infalling head-tail source, strongly-bent jets, a 100kpc radio trail and intriguing narrow X-ray filaments. Supported principally by X-ray and radio continuum data, we address the merging history of the group, the nature of the X-ray filaments, the extent of gas stripping from NGC 742, and the roles of the central AGN and infalling galaxy in heating the intra-group medium.
