Query: Radio Properties of Young Stellar Objects in the Core of the Serpens
  South Infrared Dark Cloud   We present deep radio continuum observations of the star-forming core of the
Serpens 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 in
the context of young stellar populations characterized by near and far infrared
observations. Within a 5 arcmin x 5 arcmin region of interest around the
central cluster, we detect roughly eighteen radio sources, seven of which we
determine are protostellar in nature due to their radio spectral indices and
their association with infrared sources. We find evidence for a previously
undetected embedded Class 0 protostar and reaffirm Class 0 protostellar
classifications determined by previous millimeter wavelength continuum studies.
We use our infrared data to derive mid-infrared luminosities for three of our
protostellar sources and find relative agreement between the known YSO radio
luminosity vs bolometric luminosity correlation. Lastly, we marginally detect
an additional six radio sources at the 2-3 sigma level that lie within two
arcseconds of infrared YSO candidates, providing motivation for higher
sensitivity studies to clarify the nature of these sources and further probe
embedded and/or low luminosity YSOs in Serpens South.
