GMRT study of Wolf Rayet galaxies

We report multi-frequency radio continuum observations of few Wolf Rayet galaxies Mrk 8, Mrk 1089, Mrk 33, Mrk 1236 and NGC 3049 using the Giant Meter-wave Radio Telescope (GMRT). It is remarked that these galaxies have not so far been detected and studied at much lower frequencies. Our investigations reveal that many of these galaxies are detected at frequencies <;1 GHz. We estimate synchrotron spectral index after separating the thermal free-free emission and obtain α
_nt
= 1 to -0.4. The radio morphology of the galaxies resembles the UV emission seen by GALEX with and extent similar to the NIR emission from 2MASS.
