Broad-line region size and black hole mass in high-z AGN
Ismael Botti, Paulina Lira, Hagai Netzer +3
In this contribution we briefly review the reverberation mapping technique and its results for low and intermidiate luminosity AGNs. Then we present a monitoring campaign of high-l…
Advances in Reverberation Mapping
Shai Kaspi
This contribution briefly reviews the reverberation mapping technique which leads to determination of black hole masses. I focus on the emerging relation between the broad-line reg…
X-rays from the First Massive Black Holes
W. N. Brandt, C. Vignali, D. P. Schneider +7
X-ray studies of high-redshift (z > 4) active galaxies have advanced substantially over the past few years, largely due to results from the new generation of X-ray observatories. A…
Reverberation Mapping of High-Redshift, High-Luminosity Quasars
Shai Kaspi, Hagai Netzer, Dan Maoz +3
We present preliminary results from a reverberation mapping program to measure the Broad Line Region size in high-redshift, high-luminosity quasars. The observations are carried ou…
X-ray emission from the most luminous z>4 Palomar Digital Sky Survey Quasars: the Chandra view
C. Vignali, W. N. Brandt, D. P. Schneider +2
We present the results obtained from exploratory Chandra observations of nine high-redshift (z=4.09-4.51) quasars, selected from among the optically brightest Palomar Digital Sky S…
Chandra and XMM-Newton Observations of the Highest Redshift Quasars: X-rays from the Dawn of the Modern Universe
W. N. Brandt, C. Vignali, X. Fan +2
We review X-ray studies of the highest redshift (z > 4) quasars, focusing on recent advances enabled largely by the capabilities of Chandra and XMM-Newton. Included are discussions…
