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…
Probing the nature of rotation in the Pleiades, Alpha Persei, and Hyades clusters
C. J. Hao, Y. Xu, L. G. Hou +5
Unraveling the internal kinematics of open clusters is crucial for understanding their formation and evolution. However, there is a dearth of research on this topic, primarily due…
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…
Parallaxes for W49N and G048.60+0.02: Distant Star Forming Regions in the Perseus Spiral Arm
B. Zhang, M. J. Reid, K. M. Menten +4
We report trigonometric parallax measurements of 22 GHz HO masers in two massive star-forming regions from VLBA observations as part of the BeSSeL Survey. The distances of $11.…
The Parallax of W43: a Massive Star Forming Complex near the Galactic Bar
B. Zhang, L. Moscadelli, M. Sato +7
We report trigonometric parallax measurements of masers in the massive star forming complex W43 from VLBA observations as part of the BeSSeL Survey. Based on measurements of three…
Trigonometric Parallaxes of Massive Star-Forming Regions: VII. G9.62+0.20 and the Expanding 3 KPC-ARM
A. Sanna, M. J. Reid, L. Moscadelli +5
We report a trigonometric parallax of 12 GHz methanol masers associated with the massive star forming region G9.62+0.20, corresponding to a distance of 5.2+-0.6 kpc. With a local s…
Trigonometric Parallaxes of Massive Star Forming Regions: VI. Galactic Structure, Fundamental Parameters and Non-Circular Motions
M. J. Reid, K. M. Menten, X. W. Zheng +11
We are using the VLBA and the Japanese VERA project to measure trigonometric parallaxes and proper motions of masers found in high-mass star-forming regions across the Milky Way. E…
