Mapping the Quasar Main Sequence in the UV range: A Connection with the UV Fe III Emission
D. Martínez Collipal, M. L. Martínez-Aldama, A. Pandey +3
The quasar main sequence (MS) provides a consistent unification scheme for type I AGNs. This framework, constructed from the relative flux between the optical emissions $\mathrm{H}…
Observations of a Possible Transient Magnetically Arrested Accretion State in a Nearby Quasar: OQ208
Brian Punsly, Cormac Reynolds, Paola Marziani +12
OQ208 is a nearby, partially obscured quasar (z=0.077) that is a young, bright, parsec scale radio source. We assemble archival and new high frequency VLBA and VLA observations and…
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…
Investigating the origin of radio emission in candidate super-Eddington accreting black holes
Marie-Lou Gendron-Marsolais, Paola Marziani, Marco Berton +8
Recent works show that the radio power of quasars accreting at very high rates can reach surprisingly high values. These studies suggest that this radio emission might originate fr…
AGN Variability with Rubin Observatory in the 2030s
Swayamtrupta Panda, Francisco Pozo Nuñez, Hygor Benati Gonçalves +4
AGN variability offers a direct probe of accretion physics, disk structure, and black hole growth, but progress has been limited by sample size, cadence heterogeneity, and photomet…
