| dc.description.abstract | We report the GMRT detection of H I absorption in the high- redshift red quasar 3C 190 at a redshift of 1.1946. The most interesting result is that the peak of the H I absorption is blue shifted by - 250 kms-1 with respect to the optical emission lines. The H I absorption profile indicates the presence of multiple components and the peak absorption is at 647.728 MHz. The FWHM of this absorption feature is 185 ± 7 kms-1and the peak optical depth is 0.012. The corresponding atomic hydrogen column density is 3.98 x 10^20 (T,/100K) cm-2. | en |
