Black hole mass and spin estimates of the most distant quasars
Samuele Campitiello, Annalisa Celotti, Gabriele Ghisellini +1
We investigate the properties of the most distant quasars ULASJ134208.10+092838.61 (), ULASJ112001.48+064124.3 () and DELSJ003836.10-152723.6 () study…
On the orientation of Narrow Line Seyfert I
Tullia Sbarrato, Massimo Dotti, Giancarlo Ghirlanda +1
We study a sample of Narrow-line Seyfert 1 galaxies (NLS1) in their optical and radio features, in order to understand the differences between their radio silent, radio-loud and ra…
AGN mass estimates in large spectroscopic surveys: the effect of host galaxy light
Ludovica Varisco, Tullia Sbarrato, Giorgio Calderone +1
Virial-based methods for estimating active supermassive black hole masses are now commonly used on extremely large spectroscopic quasar catalogues. Most spectral analyses, though,…
