Optical and cm follow-ups of the Changing-Look event in Mkn 590
Biswaraj Palit, Abhijeet Borkar, Agata Różańska +5
The Changing-Look active galactic nucleus Mkn 590 is currently in a rejuvenated state, exhibiting a contemporaneous flux rise across X-rays, UV, optical and cm wavelengths. In this…
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 Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
AT 2019aalc: a Bowen Fluorescence Flare With a Precursor Flare in an Active Galactic Nucleus
Marzena Śniegowska, Benny Trakhtenbrot, Lydia Makrygianni +10
AT 2019aalc is a peculiar sequence of highly variable emission events observed towards the nucleus of the broad-line AGN SDSS J152416.66+045119.0. The system exhibited two distinct…
Markarian 590: The AGN Awakens
Biswaraj Palit, Marzena Śniegowska, Alex Markowitz +3
Changing-Look AGN (CLAGN) Mkn 590 recently underwent a sudden re-ignition, marked by substantial increases in optical/UV and X-ray continuum flux since last couple of years. Swift-…
