Fundamental differences in the radio properties of red and blue quasars: evolution strongly favoured over orientation
Lizelke Klindt, David M. Alexander, David J. Rosario +2
A minority of the optically selected quasar population are red at optical wavelengths due to the presence of dust along the line-of-sight. A key focus of many red quasar studies is…
The physical relation between disc and coronal emission in quasars
E. Lusso, G. Risaliti
We propose a modified version of the observed non-linear relation between the X-ray (2 keV) and the ultraviolet (2500 Å) emission in quasars (i.e. )…
A Hubble diagram for quasars
Susanna Bisogni, Guido Risaliti, Elisabeta Lusso
The cosmological model is at present not tested between the redshift of the farthest observed supernovae (z ~ 1.4) and that of the Cosmic Microwave Background (z ~ 1,100). Here we…
EW[OIII] as an orientation indicator for quasars: implications for the torus
Susanna Bisogni, Alessandro Marconi, Guido Risaliti +1
We present an analysis of the average spectral properties of 12,000 SDSS quasars as a function of accretion disc inclination, as measured from the equivalent width of the [O III] 5…
Type 2 AGN host galaxies in the Chandra-COSMOS Legacy Survey: No Evidence of AGN-driven Quenching
Hyewon Suh, Francesca Civano, Guenther Hasinger +16
We investigate the star formation properties of a large sample of ~2300 X-ray-selected Type 2 Active Galactic Nuclei (AGNs) host galaxies out to z~3 in the Chandra COSMOS Legacy Su…
Cosmological test with the QSO Hubble diagram
M. Lopez-Corredoira, F. Melia, E. Lusso +1
A Hubble diagram (HD) has recently been constructed in the redshift range 0<z<6.5 using a non-linear relation between the ultraviolet and X-ray luminosities of QSOs. The Type Ia SN…
