NuSTAR Reveals Extreme Absorption in z < 0.5 Type 2 Quasars
G. B. Lansbury, P. Gandhi, D. M. Alexander +27
The intrinsic column density (NH) distribution of quasars is poorly known. At the high obscuration end of the quasar population and for redshifts z<1, the X-ray spectra can only be…
Broad Iron Emission from Gravitationally Lensed Quasars Observed by Chandra
D. J. Walton, M. T. Reynolds, J. M. Miller +3
Recent work has demonstrated the potential of gravitationally lensed quasars to extend measurements of black hole spin out to high-redshift with the current generation of X-ray obs…
Black hole feedback in the luminous quasar PDS 456
E. Nardini, J. N. Reeves, J. Gofford +17
The evolution of galaxies is connected to the growth of supermassive black holes in their centers. During the quasar phase, a huge luminosity is released as matter falls onto the b…
