The Quasar Main Sequence of Super-Eddington NLSy1 Galaxies
Alberto DomÃnguez, Alberto Domínguez, Suvendu Rakshit +3
The quasar main sequence, or Eigenvector 1 (EV1), describes the optical diversity of active galactic nuclei (AGN), with Narrow-Line Seyfert 1 (NLSy1) galaxies anchoring the high-ac…
Narrow-Line Seyfert 1 Galaxies in the Dark Energy Spectroscopic Instrument Data Release 1
Vaidehi S. Paliya, Suvendu Rakshit, Alberto Dominguez +2
Narrow-line Seyfert 1 (NLSy1) galaxies are peculiar active galactic nuclei (AGN) known to exhibit a variety of intriguing observational features from low-frequency radio waves to h…
The broadband spectral energy distribution of candidate neutrino blazars
Athira M Bharathan, C. S. Stalin, Markus Böttcher +3
Blazars, the jet dominated class of AGN comprising flat spectrum radio quasars (FSRQs) and BL Lac objects (BL Lacs) are now increasingly identified as potential sources of high ene…
Ultraviolet variability in Radio-Loud Active Galactic Nuclei observed by UVIT onboard AstroSat
M. Reshma, C. S. Stalin, Amit Kumar Mandal +3
Radio-loud active galactic nuclei (AGN) are among the most luminous objects in the Universe, emitting radiation from low-energy radio waves to high energy -rays. They are well…
Stratification of the AGN-Driven multi-phase outflows in the dwarf Seyfert galaxy NGC 4395
Payel Nandi, Luis Colina, Rogemar A. Riffel +5
We present a multi-wavelength study of nuclear outflows in the nearby dwarf Seyfert galaxy NGC~4395, which hosts an intermediate-mass black hole. Using \textit{JWST}/NIRSpec and MI…
Detection of time delay between UV and X-ray variability in Mrk 1044 using AstroSat observations
M. Reshma, C. S. Stalin, Amit Kumar Mandal +3
Active galactic nuclei are known to exhibit flux variations across the entire electromagnetic spectrum. Among these, correlations between UV/optical and X-ray flux variations serve…
