An updated model for the Perseus Spiral Arm from Trigonometric Parallax and 3-dimensional kinematic distances of distant massive stars
Lucas J. Hyland, Mark J. Reid, Simon P. Ellingsen +3
We report trigonometric parallaxes and proper motions for three water masers and one methanol maser obtained with the VLBA as part of the BeSSeL Survey. Incorporating these paralla…
Compact vs. Scattered: Suitability of Southern 6.7GHz Methanol Masers for VLBI astrometry
Lucas J. Hyland, Simon P. Ellingsen, Mark J. Reid
The 6.7~GHz methanol maser transition is exclusively associated with young, high-mass stars and represents a potential target for astrometric studies, including accurate determinat…
On the Structure of the Sagittarius Spiral Arm in the Inner Milky Way
S. B. Bian, Y. W. Wu, Y. Xu +6
We report measurements of trigonometric parallax and proper motion for two 6.7 GHz methanol and two 22 GHz water masers located in the far portion of the Sagittarius spiral arm as…
First Parallax Measurements Towards a 6.7 GHz Methanol Maser with the Australian Long Baseline Array - Distance to G339.884-1.259
V. Krishnan, S. P. Ellingsen, M. J. Reid +23
We have conducted the first parallax and proper motion measurements of 6.7 GHz methanol maser emission using the Australian Long Baseline Array (LBA). The parallax of G339.8841.…
