Near Infrared spectroscopic observations of high redshift C~{\sc i} absorbers
Siwei Zou, Patrick Petitjean, Pasquier Noterdaeme +5
We study a sample of 17 z>1.5 absorbers selected based on the presence of strong CI absorption lines in SDSS spectra and observed with the ESO-VLT spectrograph X-shooter. We derive…
The MeerKAT Absorption Line Survey (MALS)
N. Gupta, R. Srianand, W. Baan +41
Deep galaxy surveys have revealed that the global star formation rate (SFR) density in the Universe peaks at 1 < z < 2 and sharply declines towards z = 0. But a clear picture of th…
CO-dark molecular gas at high redshift: very large H content and high pressure in a low metallicity damped Lyman-alpha system
S. A. Balashev, P. Noterdaeme, H. Rahmani +6
We present a detailed analysis of a H-rich, extremely strong intervening Damped Ly- Absorption system (DLA) at towards the quasar J0843+0221, observe…
[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…
Efficient cold outflows driven by cosmic rays in high redshift galaxies and their global effects on the IGM
Saumyadip Samui, Kandaswamy Subramanian, Raghunathan Srianand
We present semi-analytical models of galactic outflows in high redshift galaxies driven by both hot thermal gas and non-thermal cosmic rays. Thermal pressure alone may not sustain…
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…
