AGN X-ray variability in the XMM-COSMOS survey
G. Lanzuisi, G. Ponti, M. Salvato +18
We took advantage of the observations carried out by XMM in the COSMOS field during 3.5 years, to study the long term variability of a large sample of AGN (638 sources), in a wide…
A statistical relation between the X-ray spectral index and Eddington ratio of active galactic nuclei in deep surveys
M. Brightman, J. D. Silverman, V. Mainieri +33
We present an investigation into how well the properties of the accretion flow onto a supermassive black hole may be coupled to those of the overlying hot corona. To do so, we spec…
A comparative analysis of virial black-hole mass estimates of moderate-luminosity active galactic nuclei using Subaru/FMOS
Kenta Matsuoka, John D. Silverman, Malte Schramm +27
We present an analysis of broad emission lines observed in moderate-luminosity active galactic nuclei (AGNs), typical of those found in X-ray surveys of deep fields, with the aim t…
