Discovery of 21 New Changing-look AGNs in Northern Sky
Qian Yang, Xue-Bing Wu, Xiaohui Fan +12
The rare case of changing-look (CL) AGNs, with the appearance or disappearance of broad Balmer emission lines within a few years, challenges our understanding of the AGN unified mo…
Discovery of a new, 2.2 Mpc Giant Radio Galaxy at a redshift of 0.57
Biny Sebastian, C. H. Ishwara-Chandra, Ravi Joshi +1
We report the discovery of one of the largest and most distant Giant Radio Galaxy (GRG) in the Lynx field which was discovered using deep Giant Metre-wave Radio Telescope (GMRT) 15…
On the incidence of MgII absorbers along the blazar sightlines
S. Mishra, H. Chand, Gopal-Krishna +3
It is widely believed that the cool gas clouds traced by MgII absorption, within a velocity offset of 5000 km/s relative to the background quasar are mostly associated with the qua…
[O II] nebular emission from Mg II absorbers: Star formation associated with the absorbing gas
Ravi Joshi, Raghunathan Srianand, Patrick Petitjean +1
We present nebular emission associated with 198 strong Mg II absorbers at 0.35 1.1 in the fibre spectra of quasars from the Sloan Digital Sky Survey. Measured [O II] lu…
HI 21-cm absorption from strong MgII absorbers
Rajeshwari Dutta, Raghunathan Srianand, Neeraj Gupta +1
We have searched for HI 21-cm absorption in 11 strong MgII systems ((MgII ) Å) at using the Giant Metrewave Radio Telescope. We have detected…
