Compact Objects Revealed by SKA and SKA-VLBI
Z. H. Lin, Y. J. Li, C. J. Hao +4
Compact objects represent a crucial interdisciplinary frontier between astronomy and fundamental physics.The SKA/SKA-VLBI, with exceptional sensitivity (at Jy levels) and ultrah…
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…
Local spiral structure based on the Gaia EDR3 parallaxes
Y. Xu, L. G. Hou, S. B. Bian +4
Context. The astrometric satellite Gaia is expected to significantly increase our knowledge as to the properties of the Milky Way. The Gaia Early Data Release 3 (Gaia EDR3) provide…
Anomalous peculiar motions of high-mass young stars in the Scutum spiral arm
K. Immer, J. Li, L. H. Quiroga-Nuñez +4
We present trigonometric parallax and proper motion measurements toward 22 GHz water and 6.7 GHz methanol masers in 16 high-mass star-forming regions. These sources are all located…
A comparison of the local spiral structure from Gaia DR2 and VLBI maser parallaxes
Y. Xu, S. B. Bian, M. J. Reid +8
Context. The Gaia mission has released the second data set (Gaia DR2), which contains parallaxes and proper motions for a large number of massive, young stars. Aims. We investigate…
