Description
The statistical properties of Supermassive Black Holes in the local Universe provide both direct and indirect constraints on theoretical models of BH formation, growth and co-evolution with their host galaxies. In this talk, I will present studies of the local distribution of X-ray selected AGN carried out thanks to the largest survey of the kind, the eROSITA All-Sky Survey. I will focus in particular on robust statistical estimates of the incidence of active black hole as a function of the local galaxy properties across a wide range in stellar mass, including some of the most stringent constraints on the nuclear activity in low-mass galaxies.
