Multi-epoch VLBI of a double maser super burst
Ross A. Burns, Olga Bayandina, Gabor Orosz +20
In a rare and spectacular display, two well-known massive star forming regions, W49N and G25.65+1.05, recently underwent maser 'super burst' - their fluxes suddenly increasing abov…
The extraordinary outburst in the massive protostellar system NGC6334I-MM1: Flaring of the water masers in a north-south bipolar outflow driven by MM1B
C. L. Brogan, T. R. Hunter, C. J. Cyganowski +6
We compare multi-epoch sub-arcsecond VLA imaging of the 22 GHz water masers toward the massive protocluster NGC6334I observed before and after the recent outburst of MM1B in (sub)m…
Science with an ngVLA: Understanding Massive Star Formation through Maser Imaging
Todd R. Hunter, Crystal L. Brogan, Anna Bartkiewicz +6
Imaging the bright maser emission produced by several molecular species at centimeter wavelengths is an essential tool for understanding the process of massive star formation becau…
A Masing Event in NGC6334I: Contemporaneous Flaring of Hydroxyl, Methanol and Water Masers
G. C. MacLeod, D. P. Smits, S. Goedhart +7
As a product of the maser monitoring program with the 26m telescope of the Hartebeesthoek Radio Astronomy Observatory (HartRAO), we present an unprecedented, contemporaneous flarin…
Improved Selection Criteria for HII Regions, based on IRAS Sources
Qing-Zeng Yan, Ye Xu, A. J. Walsh +6
We present new criteria for selecting HII regions from the Infrared Astronomical Satellite (IRAS) Point Source catalogue (PSC), based on an HII region catalogue derived manually fr…
The Extraordinary Outburst in the Massive Protostellar System NGC6334I-MM1: Emergence of Strong 6.7 GHz Methanol Masers
T. R. Hunter, C. L. Brogan, G. C. MacLeod +7
We report the first sub-arcsecond VLA imaging of 6 GHz continuum, methanol maser, and excited-state hydroxyl maser emission toward the massive protostellar cluster NGC6334I followi…
