Constraining the Low-mass End of the Black Hole Mass Function and the Active Fraction of the Intermediate-mass Black Holes
We investigate the black hole mass function (BHMF) and the Eddington ratio distribution function (ERDF), focusing on the intermediate-mass black holes (IMBHs) with masses down to M _• ∼ 10 ^4 M _⊙ . Based on the active galactic nuclei (AGNs) with a detected broad H α emission line, we construct a sa...
