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…
Ammonia and CO Outflow around 6.7 GHz Methanol Masers
F. C. Li, Y. Xu, Y. W. Wu +4
Single point observations are presented in NH3 (1,1) and (2,2) inversion transitions using the Effelsberg 100 m telescope for a sample of 100 6.7 GHz methanol masers and mapping ob…
Trigonometric Parallaxes of Star Forming Regions in the Scutum Spiral Arm
M. Sato, Y. W. Wu, K. Immer +6
We report measurements of trigonometric parallaxes for six high-mass star-forming regions in the Scutum spiral arm of the Milky Way as part of the BeSSeL Survey. Combining our meas…
Trigonometric parallaxes of star forming regions in the Sagittarius spiral arm
Y. W. Wu, M. Sato, M. J. Reid +7
We report measurements of parallaxes and proper motions of ten high-mass star-forming regions in the Sagittarius spiral arm of the Milky Way as part of the BeSSeL Survey with the V…
Ammonia and CO observations toward low-luminosity 6.7-GHz methanol masers
Y. W. Wu, Y. Xu, J. D. Pandian +4
To investigate whether distinctions exist between low and high-luminosity Class II 6.7-GHz methanol masers, we have undertaken multi-line mapping observations of various molecular…
