We present deep radio continuum observations of the star-forming core of theSerpens South Infrared Dark Cloud with the Karl G. Jansky Very Large Array(VLA). Observations were conducted in two bands centered at 7.25 GHz (4.14 cm)and 4.75 GHz (6.31 cm) with an rms of 8.5 and 11.1 microJy/beam, respectively.We also use 2MASS, Spitzer and Herschel data to put our radio observations inthe context of young stellar populations characterized by near and far infraredobservations. Within a 5 arcmin x 5 arcmin region of interest around thecentral cluster, we detect roughly eighteen radio sources, seven of which wedetermine are protostellar in nature due to their radio spectral indices andtheir association with infrared sources. We find evidence for a previouslyundetected embedded Class 0 protostar and reaffirm Class 0 protostellarclassifications determined by previous millimeter wavelength continuum studies.We use our infrared data to derive mid-infrared luminosities for three of ourprotostellar sources and find relative agreement between the known YSO radioluminosity vs bolometric luminosity correlation. Lastly, we marginally detectan additional six radio sources at the 2-3 sigma level that lie within twoarcseconds of infrared YSO candidates, providing motivation for highersensitivity studies to clarify the nature of these sources and further probeembedded and/or low luminosity YSOs in Serpens South.
