Observational signatures of AGN feedback across cosmic time

Dominika Wylezalek , ZAH/ARI
AGN feedback is now widely considered to be one of the main drivers in regulating the growth of massive galaxies. In my talk I will describe several efforts to understand the power, reach and impact of AGN feedback processes. Using SDSS-IV MaNGA at low-z, we find significant evidence for AGN signatures even in low-luminosity AGN. Using molecular gas as a tracer, we are investigating if / how feedback may impact and quench galaxies at low-z. At higher redshift, we find that outflows can indeed suppress star formation in their hosts, consistent with the AGN having a 'negative' impact. However, both star formation and quasar activity peak at z ~ 2-3 where AGN are expected to impact the build-up of stellar mass the most. Our team recently discovered a unique population of luminous high-z quasars (ERQs) with extreme outflow properties. At the same time, more and more exotic AGN populations with extreme signatures are being discovered at that redshift. These populations are ideal to obtain a census of the overall mass and energy budget of both outflow and infall/feeding from the CGM, an essential requirement to probe the detailed and full feedback loop. I will present recent efforts in our group to characterise feedback processes in powerful AGN on CGM scales at and near cosmic noon.

Finally, I will also introduce the JWST ERS Program "Q3D" which will study the impact of three carefully selected luminous quasars on their hosts. Our program will serve as a pathfinder for JWST science investigations in IFU mode.
