VLBI observations of the G25.65+1.05 water maser superburst
R. A. Burns, G. Orosz, O. Bayandina +23
This paper reports observations of a 22 GHz water maser `superburst' in the G25.65+1.05 massive star forming region, conducted in response to an alert from the Maser Monitoring Org…
Anomalous peculiar motions of high-mass young stars in the Scutum spiral arm
K. Immer, J. Li, L. H. Quiroga-Nuñez +4
We present trigonometric parallax and proper motion measurements toward 22 GHz water and 6.7 GHz methanol masers in 16 high-mass star-forming regions. These sources are all located…
Trigonometric Parallaxes Of High-Mass Star Forming Regions: Our View Of The Milky Way
M. J. Reid, K. M. Menten, A. Brunthaler +15
We compile and analyze ~200 trigonometric parallaxes and proper motions of molecular masers associated with very young high-mass stars. These measurements strongly suggest that the…
Resolving the distance controversy for Sharpless 269: A possible kink in the outer arm
L. H. Quiroga-Nuñez, K. Immer, H. J. van Langevelde +2
Sharpless 269 (S269) is one of a few HII regions in the outer spiral arm of the Milky Way with strong water maser emission. Based on data from the Very Long Baseline Interferometry…
The dynamical evolution of molecular clouds near the Galactic Centre - II. Spatial structure and kinematics of simulated clouds
J. M. D. Kruijssen, J. E. Dale, S. N. Longmore +16
The evolution of molecular clouds in galactic centres is thought to differ from that in galactic discs due to a significant influence of the external gravitational potential. We pr…
The Synergy between VLBI and Gaia astrometry
Huib van Langevelde, Luis Henry Quiroga-Nuñez, Wouter Vlemmings +10
With the publication of Gaia DR2, 1.3 billion stars now have public parallax and proper motion measurements. In this contribution, we compare the results for sources that have both…
