SCOTCH III: Complete search for Hypercompact HII regions in the fourth quadrant
A. L. Patel, J. S. Urquhart, A. Y. Yang +7
We present high-frequency (18-24 GHz) radio continuum observations towards 335 methanol masers, excellent signposts for young, embedded high-mass protostars. These complete the sea…
Dynamic Massive Star Formation: Radio Flux Variability in UCHII Regions
A. Y. Yang, M. A. Thompson, J. S. Urquhart +7
Context: Theoretical models of early accretion during the formation process of massive stars have predicted that HII regions exhibit radio variability on timescales of decades. How…
SCOTCH Search for Clandestine Optically Thick Compact HII regions II
A. L. Patel, J. S. Urquhart, A. Y. Yang +4
In this study we present 18 to 24 GHz and high angular resolution radio wavelength Australia Telescope Compact Array follow up observations towards a sample of 39 HC HII region can…
SCOTCH -- Search for Clandestine Optically Thick Compact HIIs
A. L. Patel, J. S. Urquhart, A. Y. Yang +7
This study uses archival high frequency continuum data to expand the search for Hypercompact HII regions and determine the conditions at which they appear, as this stage high mass…
