The Impact of Supermassive Black Holes on Milky Way and Andromeda-mass Progenitors Since z = 2.5

This work investigates the supermassive black hole-galaxy co-evolution of Milky Way and Andromeda-mass progenitors by tracking their mean black hole accretion rate (BHAR) and mean star-formation rate (SFR) since z = 2.5. We place these results in the context of galaxy quenching by comparing the evolution of the BHARs and SFRs to the quenching rate over similar timescales. This work will help provide greater insight into the formation processes of Milky Way and Andromeda-mass progenitors and to what extent the feedback from supermassive black hole accretion plays in the quenching of galaxies over cosmic time.
