The incidence of X-ray selected AGN in the nearby Universe by Dr. Keir Birchall from the University of Leicester

Abstract: Tracing AGN activity across cosmic time has been crucial in finding evidence for SMBH and galactic co-evolution. However, these samples tend to be incomplete, being dominated by brighter, more actively accreting AGN. In this talk, I will present results from my completeness-corrected measurements of the X-ray AGN population in the nearby Universe (z < 0.35). Using the resulting X-ray luminosity and Eddington ratio distributions, I will highlight how AGN incidence is dependent on host galaxy stellar mass, redshift, and star-formation rate

The Seminar will be in person from 3pm until 4pm in C36 in the Physics Department, followed by an informal discussion with coffee and biscuits immediately afterwards. The title and abstract for the talk can be found below.
