High sensitivity low frequency radio observations of cD galaxies
S. Giacintucci, T. Venturi, S. Bardelli +3
We present the GMRT 235 MHz images of three radio galaxies and 610 MHz images of two sources belonging to a complete sample of cD galaxies in rich and poor galaxy clusters. The ana…
Detecting cold gas at intermediate redshifts: GMRT survey using Mg II systems
Neeraj Gupta, R. Srianand, P. Petitjean +3
Intervening HI 21-cm absorption systems at z > 1.0 are very rare and only 4 confirmed detections have been reported in the literature. Despite their scarcity, they provide interest…
3C254: MERLIN observations of a highly asymmetric quasar
P. Thomasson, D. J. Saikia, T. W. B. Muxlow
Multifrequency, high-resolution radio observations of the quasar 3C254 using MERLIN are presented. The quasar has a highly asymmetric radio structure, with the eastern component of…
Associated 21-cm HI absorption towards the radio galaxy 3C452 (J2245+3941)
Neeraj Gupta, D. J. Saikia
We report the detection of 21-cm HI absorption towards the core of the Fanaroff-Riley II radio galaxy 3C452 (J2245+3941). The absorption profile is well resolved into three compone…
Unification scheme and the distribution of neutral gas in compact radio sources
Neeraj Gupta, D. J. Saikia
We examine the consistency of HI properties with the unification scheme for radio galaxies and quasars, and any correlation with the symmetry parameters for a sample of CSS and GPS…
