Quasar emission lines as virial luminosity estimators
P. Marziani, E. Bon, N. Bon +6
Quasars accreting matter at very high rates (known as extreme Population A [xA]) may provide a new class of distance indicators covering cosmic epochs from present day up to less t…
Radio-loudness along the quasar main sequence
V. Ganci, P. Marziani, M. D'Onofrio +4
Following the established view of the AGNs inner workings, an AGN is radio-loud (RL) if associated with relativistic ejections emitting a radio synchrotron spectrum (i.e., a jetted…
Black hole mass estimates in quasars - A comparative analysis of high- and low-ionization lines
P. Marziani, A. del Olmo, M. A. Martinez-Carballo +7
The inter-line comparison between high- and low-ionization emission lines has yielded a wealth of information on the quasar broad line region (BLR) structure and dynamics, includin…
Quasars: from the Physics of Line Formation to Cosmology
P. Marziani, E. Bon, N. Bon +6
Quasars accreting matter at very high rates (known as extreme Population A [xA] or super-Eddington accreting massive black holes) provide a new class of distance indicators coverin…
