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…
3D spectroscopy with GTC-MEGARA of the triple AGN candidate in SDSS J102700.40+174900.8
Erika Benítez, Héctor Ibarra-Medel, Castalia Alenka Negrete +4
Triple AGN systems are expected to be the result of the hierarchical model of galaxy formation. Since there are very few of them confirmed as such, we present the results of a new…
The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
Statistical analysis of AlIII 1860 and CIII] 1909 emission lines as virial black hole mass estimators in quasars
T. M. Buendia-Rios, C. A. Negrete, P. Marziani +1
We test the usefulness of the intermediate ionisation lines AlIII 1860 and CIII] 1909 as reliable virial mass estimators for quasars. We identify a sample of 309 quasars from the S…
