GMRT radio continuum study of Wolf Rayet galaxies I: NGC 4214 and NGC 4449
Shweta Srivastava, Nimisha Kantharia, Aritra Basu +2
We report low frequency observations of Wolf-Rayet galaxies, NGC 4214 and NGC 4449 at 610, 325 and 150 MHz, using the Giant Meterwave Radio Telescope (GMRT). We detect diffuse exte…
Multiwavelength characterization of faint Ultra Steep Spectrum radio sources : A search for high-redshift radio galaxies
Veeresh Singh, Alexandre Beelen, Yogesh Wadadekar +9
Ultra Steep Spectrum (USS) radio sources are one of the efficient tracers of powerful High-z Radio Galaxies (HzRGs). In contrast to searches for powerful HzRGs from radio surveys o…
Unveiling the population of high-redshift radio galaxies using centimeter GMRT survey
Veeresh Singh, Alexandre Beelen, Yogesh Wadadekar +5
Ultra Steep Spectrum (USS) radio sources are one of the efficient tracers of High Redshift Radio Galaxies (HzRGs). To search for HzRGs candidates, we investigate properties of a la…
Equipartition magnetic fields and star formation rates in normal galaxies at sub-kpc scales
Aritra Basu, Subhashis Roy
We studied the total magnetic field strength in normal star-forming galaxies estimated using energy equipartition assumption. Using the well known radio--far infrared correlation w…
