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…
Feeding frenzy in the mighty black holes: what we could learn from them?
Swayamtrupta Panda, Hygor Benati Gonçalves, Thaisa Storchi-Bergmann +14
Eddington ratio is a paramount parameter governing the accretion history and life cycles of Active Galactic Nuclei (AGNs). This short review presents a multi-faceted view of the im…
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…
From sub-solar to super-solar chemical abundances along the quasar main sequence
Paola Marziani, Alberto Floris, Alice Deconto-Machado +8
The 4D Eigenvector 1 sequence has proven to be a highly effective tool for organizing observational and physical properties of type 1 active galactic nuclei (AGN). In this paper, w…
High Metal Content of Highly Accreting Quasars: Analysis of an Extended Sample
Karla Garnica, C. Alenka Negrete, Paola Marziani +3
We present an analysis of UV spectra of quasars at intermediate redshifts believed to belong to the extreme Population A (xA), aimed to estimate the chemical abundances of the broa…
