AGN feedback: The interactions of AGN radiation, jets and winds with the host galaxyThe supermassive black holes in the centers of galaxies accrete gas and launch jets, fast winds, oremit copious amounts of radiation. The jets, winds, and radiation may impact the gas in host galaxy on
scales ranging from fractions of parsecs to hundreds of kiloparsec. This cycle of matter andenergy affects the evolution of galaxies and is termed the “feedback cycle of galaxy formation”. It leads
to a regulated history of star-formation, evidenced through the luminosity functions of galaxies, and tothe coevolution of the central supermassive black hole and the galaxy, evidenced throughthe scaling relations such as the Magorrian relation. We are pursuing a numerically intensive projectrunning 3-dimensional relativistic hydrodynamic and radiation-hydrodynamic simulations withmultiphase gas aimed at elucidating the physics of the mass and energy transfer in the feedback cycle
and the effects of jets, winds, and radiation on star-formation and black hole accretion. In recent work
we have: 1) conducted simulations of jets interacting with massive disc galaxies and inducing turbulenceand star-formation within. A strong dependence of the interaction on the inclination of the disc was
discovered. (Mukherjee, Bicknell, Wagner, et al 2018); 2) performed high-resolution wind-cloudinteraction simulations, following the fragmentation, compression and destruction of a turbulent cloud
embedded in a fast astrophysical flow. The work uncovered the very differing of evolution of turbulent
clouds dominated by solenoidal modes, and those dominated by compressive modes (Banda-Barragán,
including Wagner, 2019); 3) investigated how the jet in 4C 31.04 is shocking and exciting molecularand ionized gas in the circumnuclear region of the galaxy using adaptive optics-assisted H- and K-band
integral field Gemini/NIFS observation. A picture emergers in which the jet is directly dispersing the- 45 -
