The quasar M_bh - M_host relation through Cosmic Time II - Evidence for evolution from z=3 to the present age
R. Decarli, R. Falomo, A. Treves +3
We study the dependence of the M_bh - M_host relation on the redshift up to z=3 for a sample of 96 quasars the host galaxy luminosities of which are known. Black hole masses were e…
The quasar M_bh - M_host relation through Cosmic Time I - Dataset and black hole masses
R. Decarli, R. Falomo, A. Treves +3
We study the M_bh - M_host relation as a function of Cosmic Time in a sample of 96 quasars from z=3 to the present epoch. In this paper we describe the sample, the data sources and…
Downsizing of supermassive black holes from the SDSS quasar survey (II). Extension to z~4
Marzia Labita, Roberto Decarli, Aldo Treves +1
Starting from the quasar sample of the Sloan Digital Sky Survey (SDSS) for which the CIV line is observed, we use an analysis scheme to derive the z-dependence of the maximum mass…
Downsizing of supermassive black holes from the SDSS quasar survey
Marzia Labita, Roberto Decarli, Aldo Treves +1
Starting from the ~50000 quasars of the Sloan Digital Sky Survey for which MgII line width and 3000 A monochromatic flux are available, we aim to study the dependence of the mass o…
On the geometry of broad emission region in quasars
R. Decarli, M. Labita, A. Treves +1
We study the geometry of the Hbeta broad emission region by comparing the M_BH values derived from Hbeta through the virial relation with those obtained from the host galaxy lumino…
The NIR to UV continuum of radio loud vs. radio quiet quasars
Marzia Labita, Aldo Treves, Renato Falomo
Starting from a sample of SDSS quasars appearing also in the 2MASS survey, we study the continuum properties of about 1000 objects observed in 8 bands, from NIR to UV. We construct…
