Detecting cold gas at intermediate redshifts: GMRT survey using Mg II systems
Neeraj Gupta, R. Srianand, P. Petitjean +3
Intervening HI 21-cm absorption systems at z > 1.0 are very rare and only 4 confirmed detections have been reported in the literature. Despite their scarcity, they provide interest…

Multiwavelength investigation of a near-solar metallicity sub-DLA at z =1.3647 towards PKS 0237-233
Raghunathan Srianand, Neeraj Gupta, Patrick Petitjean
We searched for 21-cm absorption associated with the z_abs = 1.3647 absorption system toward PKS 0237-233 using the GMRT. A high quality UVES spectrum shows that C I and C I* are d…
