Intermediate-mass Black Holes in Galactic Nuclei

Abstract

We present the first homogeneous sample of intermediate-mass black hole candidates in active galactic nuclei. Starting with broad-line active nuclei from the Sloan Digital Sky Survey, we use the linewidth-luminosity-mass scaling relation to select a sample of 19 galaxies in the mass range MBH ≈ 8 × 10 4 − 10 M⊙. In contrast to the local active galaxy… (More)
