SuperMIGHTEE : Spectral Ages of Remnant Radio Galaxy Candidates in the XMM-LSS Field
Sushant Dutta, Veeresh Singh, C. H. Ishwara Chandra +8
Remnant radio galaxies, whose lobes are no longer replenished by jets from the active galactic nucleus (AGN), offer key constraints on AGN duty cycles and the timescales of radio j…
Tracing AGN-Galaxy Co-Evolution with UV Line-Selected Obscured AGN
Luigi Barchiesi, Lucia Marchetti, Mattia Vaccari +11
Understanding black hole-galaxy co-evolution and the role of AGN feedback requires complete AGN samples, including heavily obscured systems. In this work, we present the first UV l…
Intra-night optical variability and radio characteristics of extremely radio-loud narrow-line Seyfert 1 galaxies
Veeresh Singh, Parveen Kumar, Avik Kumar Das +1
Narrow-line Seyfert 1 galaxies (NLS1s) are generally known to be radio-quiet Active Galactic Nuclei (AGN), but a tiny subset of them are found to be extremely radio-loud with radio…
X-ray spectral properties of dust-obscured galaxies in the XMM-SERVS coverage of the XMM-LSS field
Abhijit Kayal, Veeresh Singh
With an aim to unveil the population of obscured AGN hosted in high- dust-obscured galaxies (DOGs), we performed X-ray spectral study of DOGs ( $4.6…
