Spectral structure of X-shaped radio sources
Dharam Vir Lal, A. Pramesh Rao
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, MNRAS in pre…
3C 223.1: A source with unusual spectral properties
Dharam Vir Lal, A. Pramesh Rao
Analysis of Giant Metrewave Radio Telescope low frequency data for an X-shaped source, 3C 223.1 has revealed an unusual result. The radio morphologies of it at 240 and 610 MHz show…
Low Frequency Observations of a Head-Tail Radio Source
Dharam Vir Lal, A. Pramesh Rao
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 fi…
Seyfert galaxies: Nuclear Radio Structure and Unification
Dharam Vir Lal
We have observed a sample of Seyfert (Sy) galaxies with the global Very Long Baseline Interferometry (VLBI) to test the predictions of the unification scheme for the Sy galaxies wh…
Milliarcsec-scale radio structure of a matched sample of Seyfert 1 and Seyfert 2 galaxies
Dharam Vir Lal, Prajval Shastri, Denise C. Gabuzda
We have obtained mas-scale resolution very long baseline interferometry (VLBI) images of a sample of Seyfert 1 and Seyfert 2 galaxies at 5 GHz (wavelength, = 6 cm). The Seyfert…
3C 129 : The GMRT observations
Dharam Vir Lal, A. Pramesh Rao
We present radio maps of the head-tail radio galaxy, 3C 129 at 240 and 610 MHz using the Giant Metrewave Radio Telescope. We have studied in detail the morphology of the source and…
