Abstract:
Recent ALMA observations identified one of the most massive
star-forming cores yet observed in the Milky Way: SDC335-MM1, within
the infrared dark cloud SDC335.579-0.292. Along with an accompanying
core MM2, SDC335 appears to be in the early stages of its star
formation process. We aim to constrain the properties of the stars
forming within these two massive millimetre sources. Observations of
SDC335 at 6, 8, 23 and 25GHz were made with the Australia Telescope
Compact Array.We report the results of these continuum measurements,
which combined with archival data, allow us to build and analyse the
spectral energy distributions (SEDs) of the compact sources in SDC335.
Description:
Radio continuum images of the HII regions observed within
SDC335.579-0.292 using the Australia Telescope Compact Array (ATCA).
Observations were made at 6, 8, 23 and 25GHz with a 2GHz bandwidth at
each frequency. 6 and 8 GHz observations from June 2013 and 23 and
25GHz observations September 2013. ATCA project code C2835.
