Wolf-Rayet galaxies have a large population of massive WR stars which dominate the optical spectra of these galaxies. Some of these galaxies have been observed in the radio continuum at frequencies >1 GHz which reveal a variety of spectra ranging from power law to flat spectra. A small subset has also been observed at lower frequencies which suggest that there is no single combination of physical mechanisms that can explain all the observed spectra. However a larger sample at the low GMRT frequencies may help discriminate between the various physical models. In this ongoing study, we have observed & detected emission at 610, 240 and 150 MHz from two WR galaxies: Mrk 008 and Mrk 1089. In this poster paper we present the integrated spectra of these galaxies and the preliminary results from our study.
