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…
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…
The Distance and Size of the Red Hypergiant NML Cyg from VLBA and VLA Astrometry
B. Zhang, M. J. Reid, K. M. Menten +2
We have measured the annual parallax and proper motion of NML Cyg from multiple epoch VLBA observations of the circulstellar H2O and SiO masers. The measured parallax of NML Cyg is…
Trigonometric Parallaxes of Massive Star Forming Regions: IV. G35.20-0.74 and G35.20-1.74
B. Zhang, X. W. Zheng, M. J. Reid +4
We report trigonometric parallaxes for the high-mass star forming regions G35.20-0.74 and G35.20-1.74, corresponding to distances of 2.19 (+0.24 -0.20) kpc and 3.27 (+0.56 -0.42) k…
