System Equivalent Flux Density of a Polarimetric Tripole Radio Interferometer
A. T. Sutinjo, M. Kovaleva, Y. Xu
System equivalent flux density (SEFD) is an important figure of merit of a radio telescope. This paper aims to derive a general expression for SEFD of a polarimetric tripole interf…
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…
