Galaxy misalignments and their role in the growth of supermassive black holes
ABSTRACT:Galaxies are known to interact with each other. This interaction process often leaves an imprint that is observable in the aftermath of the interaction, such as tidal features or perturbations in the stellar and gas kinematics of the galaxy. Sometimes these perturbations can be structures (i.e. gas or stars) that are strongly misaligned or even rotating in the opposite direction with respect to the main stellar body of the galaxy. It has been suggested by simulations that misalignments may drive galaxy gas all the way to the central supermassive back hole, one of the ingredients needed to fuel the high energy activity known as Active Galactic Nuclei. In this talk I will discuss the observational evidence of these interactions and the role that they can have on the growth of supermassive black holes.
