High Energy processes in galaxies and their active nuclei are closely linked.

Similar physical processes take place in compact accreting objects in galaxies and in AGNs, albeit on different scales. Their observational similarities and differences provide us with insights on the details of the physical processes. The nature of a galaxy may affect the growth of its nuclear black hole and the presence of an AGN affects the galaxy as well, with inflow, outflow, ionizing radiation and jets.

We will explore the intimate relationship between a galaxy and its active nucleus at this meeting.
