Co-evolution of Supermassive Black Holes and their Host L ⋆ galaxies: implications for Milky Way and M31

Abstract We investigate the origin of the scatter in supermassive black hole (BH) masses among L⋆ galaxies, using the ARTEMIS and EAGLE simulations. We classify galaxies by their central BH-to-stellar mass ratios and track systems with the lowest and highest ratios (LBH and HBH,...
