Deep VLA observations of nearby star forming regions I: Barnard 59 and
  Lupus
  Barnard 59 and Lupus 1 are two nearby star-forming regions visible from the
southern hemisphere. In this manuscript, we present deep ($\sigma$ $\lesssim$
15 $ \mu$Jy) radio observations ($\nu$ = 6 GHz; $\lambda$ = 5 cm) of these
regions, and report the detection of a total of 114 sources. Thirteen of these
sources are associated with known young stellar objects, nine in Barnard 59 and
four in Lupus 1. The properties of the radio emission (spectral index and, in
some cases, polarization) suggest a thermal origin for most young stellar
objects. Only for two sources (Sz~65 and Sz~67) are there indications for a
possible non-thermal origin; more observations will be needed to ascertain the
exact nature of the radio emission in these sources. The remaining radio
detections do not have counterparts at other wavelengths, and the number of
sources detected per unit solid angle is in agreement with extragalactic number
counts. This suggests that all radio sources not associated with known young
stellar objects are background extragalactic sources.
