Deep low-frequency observations with the Giant Metrewave Radio Telescope: a search for relic radio emission
S. K. Sirothia, D. J. Saikia, C. H. Ishwara-Chandra +1
We present deep multifrequency observations using the Giant Metrewave Radio Telescope at 153, 244, 610 and 1260 MHz of a field centered on J0916+6348, to search for evidence of fos…
Low radio frequency signatures of ram pressure stripping in Virgo spiral NGC 4254
N. G. Kantharia, A. Pramesh Rao, S. K. Sirothia
We report the detection of extended low radio frequency continuum emission beyond the optical disk of the spiral galaxy NGC 4254 using the Giant Metrewave Radio Telescope. NGC 4254…
GMRT Observations of the 2006 outburst of the Nova RS Ophiuchi: First detection of emission at radio frequencies < 1.4 GHz
N. G. Kantharia, G. C. Anupama, T. P. Prabhu +4
The first low radio frequency (<1.4 GHz) detection of the outburst of the recurrent nova RS Ophiuchi is presented in this letter. Radio emission was detected at 0.61 GHz on day 20…
Radio Observations of AGN in Low Surface Brightness Galaxies
M. Das, S. S. McGaugh, N. Kantharia +1
We present preliminary results of a study of the low frequency radio continuum emission from the nuclei of Giant Low Surface Brightness (LSB) galaxies. We have mapped the emission…
The AGN and Gas Disk in the Low Surface Brightness Galaxy PGC045080
M. Das, N. Kantharia, S. Ramya +3
We present radio observations and optical spectroscopy of the giant low surface brightness (LSB) galaxy PGC 045080 (or 1300+0144). PGC 045080 is a moderately distant galaxy having…
Radio recombination lines from the largest bound atoms in space
S. V. Stepkin, A. A. Konovalenko, N. G. Kantharia +1
In this paper, we report the detection of a series of radio recombination lines (RRLs) in absorption near 26 MHz arising from the largest bound carbon atoms detected in space. Thes…
