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…
The Hard X-ray Spectrum as a Probe for Black-Hole Growth in Radio-Quiet Active Galactic Nuclei
Ohad Shemmer, W. N. Brandt, Hagai Netzer +2
We study the hard-X-ray spectral properties of ten highly luminous radio-quiet (RQ) active galactic nuclei (AGNs) at z=1.3-3.2, including new XMM-Newton observations of four of the…
Extended silicate dust emission in PG QSOs
M. Schweitzer, B. Groves, H. Netzer +9
This paper addresses the origin of the silicate emission observed in PG QSOs, based on observations with the Spitzer Space Telescope. Scenarios based on the unified model suggest t…
