Quasar radiation transforms the gas in a merging companion galaxy
Sergei Balashev, Pasquier Noterdaeme, Neeraj Gupta +7
Quasars, powered by gas accretion onto supermassive black holes, rank among the most energetic objects of the Universe. While they are thought to be ignited by galaxy mergers and a…
HI 21-cm Absorption Associated with Foreground Galaxies on Top of Quasars
Labanya Kumar Guha, Raghunathan Srianand, Rajeshwari Dutta
A systematic search for HI 21-cm absorption in Quasar-Galaxy Pairs (QGPs) provides a powerful means to map the distribution of cold gas around high-redshift star-forming galaxies.…
Circumgalactic medium of quasar host galaxies at 0.4<z<0.8 probed by strong Mg II absorption
Paryag Sharma, Raghunathan Srianand, Hum Chand +1
Using a sample of 166 projected quasar pairs we investigate the influence of active galactic nuclei on the circumgalactic medium (CGM) of the quasar host galaxies probed using stro…
