Damped Ly-alpha Absorbers in Star-forming Galaxies at z < 0.15 Detected with the Hubble Space Telescope and Implications for Galaxy Evolution
Varsha P. Kulkarni, David V. Bowen, Lorrie A. Straka +4
We report {\it HST} COS spectroscopy of 10 quasars with foreground star-forming galaxies at 0.02 0.14 within impact parameters of 1-7 kpc. We detect damped/sub-dampe…
CII*/CII ratio in high-redshift DLAs: ISM phase separation drives the observed bimodality of [CII] cooling rates
S. A. Balashev, K. N. Telikova, P. Noterdaeme
We discuss observations of CII*/CII ratios and cooling rates due to [CII]158m emission in high-redshift intervening damped Lyman- systems towards quasars. We show that th…
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…
GRB host galaxies with strong H absorption: CO-dark molecular gas at the peak of cosmic star formation
K. E. Heintz, G. Björnsson, M. Neeleman +13
We present a pilot search of CO emission in three H-absorbing, long-duration gamma-ray burst (GRB) host galaxies at z~2-3. We used the Atacama Large Millimeter/sub-millimeter A…
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…
Estimation of the CMB temperature from atomic C\,{\sc i} and molecular CO lines in the interstellar medium of early galaxies
V. V. Klimenko, A. V. Ivanchik, P. Petitjean +2
The linear increase of the cosmic microwave background (CMB) temperature with cosmological redshift, , is a prediction of the standard cosmological CDM…
