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…
Trigonometric Parallaxes of Massive Star Forming Regions: III. G59.7+0.1 and W 51 IRS2
Y. Xu, M. J. Reid, K. M. Menten +3
We report trigonometric parallaxes for G59.7+0.1 and W 51 IRS2, corresponding to distances of 2.16^{+0.10}_{-0.09} kpc and 5.1^{+2.9}_{-1.4} kpc, respectively. The distance to G59.…
Trigonometric Parallaxes of Massive Star Forming Regions: II. Cep A & NGC 7538
L. Moscadelli, M. J. Reid, K. M. Menten +3
We report trigonometric parallaxes for the sources NGC 7538 and Cep A, corresponding to distances of 2.65 [+0.12/-0.11] kpc and 0.70 [+0.04/-0.04] kpc, respectively. The distance t…
Trigonometric Parallaxes of Massive Star Forming Regions: I. S 252 & G232.6+1.0
M. J. Reid, K. M. Menten, A. Brunthaler +3
We are conducting a large program with the NRAO Very Long Baseline Array (VLBA) to measure trigonometric parallaxes of massive star-forming regions across the Milky Way. Here we re…
A high-sensitivity 6.7 GHz methanol maser survey toward H2O sources
Y. Xu, J. J. Li, K. Hachisuka +3
We present the results of a high sensitivity survey for 6.7 GHz methanol masers towards 22 GHz water maser using the 100 m Efflesberg telescope. A total of 89 sources were observed…
