Large-Scale Spiral Structure of the Milky Way Traced by Young Classical Cepheids
Z. H. Lin, C. J. Hao, D. J. Liu +5
Using 985 classical Cepheids younger than 100 Myr, we investigate the large-scale spiral structure of the Milky Way by comparing their spatial and kinematic distributions with the…
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…
What Does the Milky Way Look Like?
Y. Xu, C. J. Hao, D. J. Liu +5
In spite of much work, the overall spiral structure morphology of the Milky Way remains somewhat uncertain. In the last two decades, accurate distance measurements have provided us…
ON the Nature of the Local Spiral Arm of the Milky Way
Y. Xu, J. J. Li, M. J. Reid +6
Trigonometric parallax measurements of nine water masers associated with the Local arm of the Milky Way were carried out as part of the BeSSeL Survey using the VLBA. When combined…
Absolute positions of 6.7-GHz methanol masers
Y. Xu, M. A. Voronkov, J. D. Pandian +5
The ATCA, MERLIN and VLA interferometers were used to measure the absolute positions of 35 6.7 GHz methanol masers to subarcsecond or higher accuracy. Our measurements represent es…
