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 rotation in the Praesepe cluster
C. J. Hao, Y. Xu, S. B. Bian +4
Although a large number of Galactic open clusters (OCs) have been identified, the internal kinematic properties (e.g., rotation) of almost all the known OCs are still far from clea…
Newly detected open clusters in the Galactic disk using Gaia EDR3
C. J. Hao, Y. Xu, Z. Y. Wu +3
The astrometric satellite Gaia recently released part of its third data set, which provides a good opportunity to hunt for more open clusters in the Milky Way. In this work, we con…
Redshifted methanol absorption tracing infall motions of high-mass star formation regions
W. J. Yang, K. M. Menten, A. Y. Yang +6
Gravitational collapse is one of the most important processes in high-mass star formation. Compared with the classic blue-skewed profiles, redshifted absorption against continuum e…
Evolution of the local spiral structure of the Milky Way revealed by open clusters
C. J. Hao, Y. Xu, L. G. Hou +6
The structure and evolution of the spiral arms of our Milky Way are basic but long-standing questions in astronomy. In particular, the lifetime of spiral arms is still a puzzle and…
Trigonometric Parallaxes of Four Star-forming Regions in the Distant Inner Galaxy
Y. Xu, S. B. Bian, M. J. Reid +9
We have measured trigonometric parallaxes for four water masers associated with distant massive young stars in the inner regions of the Galaxy using the VLBA as part of the BeSSeL…
