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…
