We report the GMRT detection of associated HI 21 cm-line absorption in thez = 1.1946 red quasar 3C 190. Most of the absorption is blue-shifted with respect to the systemic redshift. The absorption, at ∼ 647.7 MHz, is broad and complex, spanning a velocity width of ∼ 600 kms−1. Since the core is self-absorbed at this frequency, the absorption is most likely towards the hotspots. Comparison of the radio and deep optical images reveal linear filaments in the optical which overlap with the brighter… Expand

An ASKAP survey for H i absorption towards dust-obscured quasars
Obscuration of quasars by accreted gas and dust, or dusty intervening galaxies, can cause active galactic nuclei (AGN) to be missed in optically selected surveys. Radio observations can overcomeExpand
