The specific accretion-rate distribution is defined as the probability of a galaxy with a given stellar mass and redshift hosting an active nucleus with a certain specific accretion rate. We find that the probability of a galaxy hosting an AGN increases with decreasing specific accretion rate. There is evidence that this trend reverses at low specific accretion rates, $\\lambda<10^{-4}-10^{-3}$ (in Eddington units). There is also a break close to the Eddi","authors_text":"A.
