Preliminary cosmological results using extreme accretors Quasar formalism
Rodrigo Sandoval-Orozco, Castalia Alenka Negrete, Paola Marziani +1
We revisited the xA Quasar formalism from the cosmological point of view, where a completely cleaned and standardized sample is compiled from different literature references. This…
Spectral Evolution and Transient Broad-Line Features in the Isolated AGN UNAM-KIAS 613
Edgar Cortes-Suárez, Paola Marziani, Héctor Manuel Hernández-Toledo +2
We present multi-epoch optical spectroscopy of the isolated elliptical galaxy UNAM-KIAS 613, hosting a low-luminosity Type 1 AGN. Analysis of archival Sloan Digital Sky Survey (SDS…
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…
