A novel black hole mass scaling relation based on coronal gas, and its dependence with the accretion disc.

Abstract (from CDS):

Using bona-fide black hole (BH) mass estimates from reverberation mapping and the line ratio [Si VI] 1.963µm/Brγbroad as tracer of the AGN ionizing continuum, a novel BH-mass scaling relation of the form log(MBH) = (6.40 ± 0.17) - (1.99 ± 0.37) x log ([Si VI]/Brγbroad), dispersion 0.47 dex, over the BH mass interval, 106-108 M☉ is found. Following on the geometrically thin accretion disc approximation and after surveying a basic parameter space for coronal lines production, we believe one of main drivers of the relation is the effective temperature of the disc, which is effectively sampled by the [Si VI] 1.963µm coronal line for the range of BH masses considered. By means of CLOUDY photoionization models, the observed anticorrelation appears to be formally in line with the thin disc prediction Tdisc ∝ MBH–1/4.
