Abstract
We discuss two methods to estimate black hole (BH) masses using X-ray data only: from the X-ray variability amplitude and from the photon index G. The first method is based on the anti-correlation between BH mass and X-ray variability amplitude. Using a sample of AGN with BH masses from reverberation mapping, we show that this method shows small intrinsic scatter. The second method is based on the correlation between G and both the Eddington ratio L bol/L Edd and the bolometric correction L bol/L 2-10keV. © International Astronomical Union 2013.

Curran, Peter; Chaty, S.; Heras, J. (2012)Context: While the sources of X-ray and radio emission in the different states of low-mass X-ray binaries are relatively well understood, the origin of the near-infrared (NIR) and optical emission is more often debated. ...
