Mapping HI 21-cm in the Klemola 31 group at z = 0.029: emission and absorption towards PKS2020-370
E. K. Maina, Abhisek Mohapatra, G. I. G. Jozsa +11
We present MeerKAT Absorption Line Survey (MALS) observations of the HI gas in the Klemola31 galaxy group (), located along the line of sight to the radio-loud quasar PKS2…
First discoveries and localisations of Fast Radio Bursts with MeerTRAP: a real-time, commensal MeerKAT survey
K. M. Rajwade, M. C. Bezuidenhout, M. Caleb +24
We report on the discovery and localization of fast radio bursts (FRBs) from the MeerTRAP project, a commensal fast radio transient-detection programme at MeerKAT in South Africa.…
Coordinated time variability of multi-phase ultra-fast outflows in J132216.25+052446.3
P. Aromal, R. Srianand, P. Petitjean
We present a time variability analysis of broad absorption lines (BAL; spread over the velocity range of 5800-29000 km/s) seen in the spectrum of J132216.25+052446.3 (z(em)= 2.0480…
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…
Multi-phase gas properties of extremely strong intervening DLAs towards quasars
A. Ranjan, R. Srianand, P. Petitjean +6
We present the results of a spectroscopic analysis of extremely strong damped Lyman-α absorbers (ESDLAs, log N(Hi)>=21.7) observed with VLT-XShooter. ESDLAs probe gas from within t…
