Evidence for a Stratified Accretion Disk Wind in AGN
P. Marziani, E. Bon, S. Panda +5
We present observational evidence supporting the presence of a stratified accretion disk wind in active galactic nuclei (AGN), based on multi-wavelength spectroscopic analysis of b…
The Disk Plus (Failed) Wind System of 3C 47: A Story of Accretion Disks and Binary Black Holes
P. Marziani, S. Terefe Mengistue, A. del Olmo +9
[Abridged] Optically thick, geometrically thin accretion disks around supermassive black holes are thought to contribute to broad-line emission in type-1 active galactic nuclei (AG…
Quasar Main Sequence unfolded by 2.5D FRADO (Natural expression of Eddington ratio, black hole mass, and inclination)
M. H. Naddaf, M. L. Martínez-Aldama, P. Marziani +2
The quasar main sequence (QMS), characterized by the Eigenvector 1 (EV1), serves as a unifying framework for classifying type-1 active galactic nuclei (AGNs) based on their diverse…
The spectral energy distribution of extreme population A quasars
Karla Garnica, Deborah Dultzin, Paola Marziani +1
Knowledge of the broad-band active galactic nuclei (AGN) spectral energy distribution (SED) that ionizes the gas-rich broad emission line region is key to understanding the various…
LBT IR observations of candidate super-Eddington quasars
T. M. Buendia-Rios, P. Marziani, C. A. Negrete +1
Quasars accreting at very high rates are believed to be prime movers of galactic evolution because of their high radiative and mechanical output. The study presented in this paper…
Super-Eddington Accretion in Quasars
P. Marziani, K. Garnica Luna, A. Floris +5
This review provides an observational perspective on the fundamental properties of super-Eddington accretion onto supermassive black holes in quasars. It begins by outlining the se…
