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…
Discovery of a damped Ly absorber originating in a spectacular interacting dwarf galaxy pair at
Erin Boettcher, Neeraj Gupta, Hsiao-Wen Chen +18
We present the discovery of neutral gas detected in both damped Ly absorption (DLA) and HI 21-cm emission outside of the stellar body of a galaxy, the first such detection in th…
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…
OH in the diffuse interstellar medium: physical modelling and prospects with upcoming SKA precursor/pathfinder surveys
Sergei Balashev, Neeraj Gupta, Daria Kosenko
Hydroxyl () is known to form efficiently in cold gas (K) along with the molecule and can be used as an efficient tracer of the diffuse molecular gas in…
uGMRT HI 21-cm absorption observations of two extremely inverted spectrum sources
Mukul Mhaskey, Surajit Paul, Neeraj Gupta +2
We report the detection of HI 21-cm absorption in a member of the rare and recently discovered class of compact radio sources, 'Extremely Inverted Spectrum Extragalactic Radio Sour…
uGMRT search for cold gas at z~1-1.4 towards red quasars
Rajeshwari Dutta, Raghunathan Srianand, Neeraj Gupta +1
We present results from our search for HI 21-cm and OH 18-cm absorption at z~1-1.4 towards red quasars showing strong MgII absorption using uGMRT. The quasars J1501+1822 and J1521+…
