Abstract : The coldest and faintest dust component in molecular clouds dominates their dust masses, so understanding their cold dust content is necessary for understanding star formation in galaxies in general. To obtain accurate dust masses, we need to estimate the radio (thermal and non-thermal) components of the overlapping millimeter emission where dust emission dominates. To this end, we have carried out GMRT observations of four SPT- and IRAS-detected galaxies at frequencies between 310 and 1300 MHz, which we combine with SUMSS 843 MHz imaging. The radio fluxes were used to estimate the non-thermal spectral indices as well as star formation rates in our galaxy sample.
