The X-Ray AGN Bias Factor at Zero Redshift
Abstract
Using an AGN sample from the INTEGRAL all-sky survey, we show that the density fluctuations of matter in the local universe translate linearly into the density fluctuations of accreting supermassive black holes. Our results imply that hard X-ray emitting AGNs are unbiased tracers of the galaxy population in the nearby universe and SMBH activity is independent of the density of galaxies.
