"Normal" FRII Radio Galaxies as a Probe of the Nature of X-Shaped Radio Sources
Dharam Vir Lal, Martin J. Hardcastle, Ralph P. Kraft
We present a multiwavelength radio study of a sample of nearby Fanaroff-Riley class II (FRII) radio galaxies, matched with the sample of known X-shaped radio sources in size, morph…
Array configuration studies for the SKA -- Implementation of figures of merit based on SDR
Dharam V. Lal, Andrei P. Lobanov
The Square Kilometre Array is going to become operational at the time when several new large optical, X-ray and Gamma-ray telescopes are expected to be working. The main drive for…
GMRT study of X-shaped radio sources
Dharam Vir Lal, A. Pramesh Rao, Martin J. Hardcastle +5
Context. The nature of X-shaped sources is a matter of considerable debate in the literature: it has even been proposed that they provide evidence for black-hole-mergers/spin-reori…
Using Fast-Switching Data to Characterize Atmospheric Phase Fluctuations at the Submillimeter Array
Dharam Vir Lal, Satoki Matsushita, Jeremy Lim
For the submillimeter band observations, we have been routinely adopting the calibration cycle time of 20-30 minutes, which is the same as any typical centimeter and millimeter ban…
The radio properties of type II quasars
Dharam Vir Lal, Luis C. Ho
Quasars (of type I) are the luminous analogs of type I Seyfert galaxies. Within the framework of unified models of active galaxies, the population of quasars of type II recently di…
GMRT observations of X-shaped radio sources
Dharam Vir Lal, A. Pramesh Rao
We present results from a study of X-shaped sources based on observations using the Giant Metrewave Radio Telescope (GMRT). These observations were motivated by our low frequency s…
