HI gas playing hide-and-seek around a powerful FRI-type quasar at z2.1
N. Gupta, R. Srianand, E. Momjian +5
We present optical spectroscopic and milli-arcsecond scale radio continuum observations of the quasar M1540-1453 ( = 2.1040.002) that shows associated HI 21-cm absorpt…
Spatially resolved Lyman- emission around radio bright quasars
Gitika Shukla, Raghunathan Srianand, Neeraj Gupta +4
We use Southern African Large Telescope (SALT) to perform long-slit spectroscopic observations of 23 newly discovered radio-loud quasars (RLQs) at . The sample consists…
MALS SALT-NOT survey of MIR-selected powerful radio-bright AGN at 0<z<3.5
N. Gupta, G. Shukla, R. Srianand +20
We present results of an optical spectroscopic survey using SALT and NOT to build a WISE mid-infrared color-based, dust-unbiased sample of powerful radio-bright (200 mJy at 1.4…
Evolution of cold gas at 2<z<5: a blind search for HI and OH absorption lines towards mid-infrared color selected radio-loud AGNs
N. Gupta, R. Srianand, G. Shukla +9
We present results from a spectroscopically blind search for associated and intervening HI 21-cm and OH 18-cm absorption lines towards 88 AGNs at using the upgraded Gi…
Lyman- emission from a WISE-selected optically faint powerful radio galaxy M151304.72-252439.7 at = 3.132
Gitika Shukla, Raghunathan Srianand, Neeraj Gupta +4
We report the detection of a large ( kpc) and luminous nebula [ = ] around an optically f…
