Black Hole Growth to z = 2 - I: Improved Virial Methods for Measuring M_BH and L/L_Edd    [PDF]

Benny Trakhtenbrot, Hagai Netzer

We analyze several large samples of AGN in order to establish the best tools required to study the evolution of black hole mass (M_BH) and normalized accretion rate (L/L_Edd). The data include spectra from the SDSS, 2QZ and 2SLAQ surveys at z<2, and a compilation of smaller samples with 0View original: http://arxiv.org/abs/1209.1096
