Low Frequency Observations of a Head-Tail Radio Source

Vir Lal, D; Pramesh Rao, A (Astronomical Society of India, 2003)

We have mapped the head-tail radio galaxy, 3C 129 at 240 and 610 MHz using the GMRT and studied the detailed morphology and spectral index variations in this object. This is the first attempt to observe a sample of head-tail ...
Optical and radio observations of the bright GRB 010222 afterglow: evidence for rapid synchrotron cooling ?

Sagar, R; Stalin, C. S; Bhattacharya, D; Pandey, S. B; Mohan, V; Castro-Tirado, A. J; Pramesh Rao, A; Trushkin, S. A; Nizhelskij, N. A; Bremer, M; Castro Ceron, J. M (Astronomical Society of India, 2001)

We report photometric observations of the optical afterglow of GRB 010222 in V, R and I passbands carried out between 22-27 February 2001 at Nainital. We determine the CCD Johnson BV and Cousins RI photometric magnitudes ...
Spectral structure of X-shaped radio sources

Vir Lal, D; Pramesh Rao, A (Astronomical Society of India, 2004-09)

Analysis of Giant Metrewave Radio Telescope low frequency data for an X-shaped source, 3C 223.1 has revealed an unusual result as discussed earlier by Lal & Rao (2004). The radio morphologies of it at 240 and 610 MHz show ...
