J1432+158: the most distant giant quasar
A. K. Singal, C. Konar, D. J. Saikia
We present low-frequency, GMRT (Giant Metrewave Radio Telescope) observations at 333 and 617 MHz of the most-distant giant quasar, J1432+158, which is at a redshift of 1.005. The r…
3C459: A highly asymmetric radio galaxy with a starburst
P. Thomasson, D. J. Saikia, T. W. B. Muxlow
Multifrequency radio observations of the radio galaxy 3C459 using MERLIN, VLA and the EVN, and an optical HST image using the F702W filter are presented. The galaxy has a very asym…
Symmetry Parameters of CSS Sources: Evidence of Fuelling?
D. J. Saikia, S. Jeyakumar, F. Mantovani +4
The compact steep spectrum (CSS) and gigahertz peaked spectrum (GPS) sources are widely believed to be young radiosources, with ages <10^6 yr. If the activity in the nucleus is fue…
Polarization asymmetry in CSS sources: evidence of AGN fuel?
D. J. Saikia, Neeraj Gupta
The compact steep spectrum and gigahertz peaked spectrum sources are widely believed to be young radio sources, with ages <10^6 yr. If the activity in the nucleus is fuelled by the…
