Multi-Band Optical Variability Characteristics of the -ray emitting blazar 1ES 0647+250 during its 2020 flare

K. Subbu Ulaganatha Pandian, C. S. Stalin, S. Muneer +4

We present a multi-band optical variability study of the -ray emitting high-synchrotron-peaked blazar 1ES~0647+250 during its enhanced optical activity in 2020. The analysis uti…

A Gamma-ray Emitting Head-Tail Radio Galaxy Swimming Through the Hot Medium of the Merging Cluster Abell 3627

Vaidehi S. Paliya, M. Böttcher, Swayamtrupta Panda +4

Head-tail radio sources are jetted active galactic nuclei (AGN) moving through the dense intracluster medium of galaxy clusters. They are extremely rare in the gamma-ray sky, likel…

The Quasar Main Sequence of Super-Eddington NLSy1 Galaxies

Alberto Domínguez, Suvendu Rakshit, Vaidehi S. Paliya +2

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…

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 k…
