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…
SDSS-V Black Hole Mapper: The Index Diagram as a tool to disentangle the influence of the Host Galaxy in Quasar spectra
C. A. Negrete, R. Sandoval-Orozco, H. Ibarra-Medel +32
We revisit the Quasar Main Sequence (QMS) by investigating the impact of the stellar component from the host galaxy (HG) on the emission line spectra of the active galactic nuclei…
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…
The properties of the obscuring material of an AGNs sample from mid-IR and X-ray simultaneous fitting
Donaji Esparza-Arredondo, Omaira Gonzalez-MartÃn, Deborah Dultzin +5
Over ten mid-infrared (mid-IR) and X-ray models are currently attempting to describe the nuclear obscuring material of active galactic nuclei (AGNs), but many questions remain unre…
