East Asian VLBI Network astrometry toward the star-forming region G040.96+02.48 in the Extreme Outer Galaxy
Xianjin Shen, Zehao Lin, Nobuyuki Sakai +18
Accurate astrometric measurements for star-forming regions located on the far side of the Milky Way remain scarce. In this work, we present the astrometric results for a 22\,GHz wa…
Sciences with Thai National Radio Telescope
Phrudth Jaroenjittichai, Koichiro Sugiyama, Busaba H. Kramer +44
This White Paper summarises potential key science topics to be achieved with Thai National Radio Telescope (TNRT). The commissioning phase has started in mid 2022. The key science…
Water Maser Survey towards off-plane O-rich AGBs around the orbital plane of the Sagittarius Stellar Stream
Yuanwei Wu, Bo Zhang, Jingjing Li +1
A 22 GHz water maser survey was conducted towards 178 O-rich AGB stars with the aim of identifying maser emission associated with the Sagittarius stellar stream. In this survey, ma…
Parallaxes for star forming regions in the inner Perseus spiral arm
Bo Zhang, Mark J. Reid, Lian Zhang +8
We report trigonometric parallax and proper motion measurements of 6.7-GHz CH3OH and 22-GHz H2O masers in eight high-mass star-forming regions (HMSFRs) based on VLBA observations a…
The Distances to Molecular Clouds at High Galactic Latitudes based on GAIA DR2
Qing-Zeng Yan, Bo Zhang, Ye Xu +4
We report the distances of molecular clouds at high Galactic latitudes (|b|>10) derived from parallax and G band extinction (A) measurements in the second Gaia da…
Improved Selection Criteria for HII Regions, based on IRAS Sources
Qing-Zeng Yan, Ye Xu, A. J. Walsh +6
We present new criteria for selecting HII regions from the Infrared Astronomical Satellite (IRAS) Point Source catalogue (PSC), based on an HII region catalogue derived manually fr…
SiO Maser Survey towards off-plane O-rich AGBs around the orbital plane of the Sagittarius Stellar Stream
Yuanwei Wu, Noriyuki Matsunaga, Ross A. Burns +1
We conducted an SiO maser survey towards 221 O-rich AGB stars with the aim of identifying maser emission associated with the Sagittarius stellar stream. In this survey, maser emiss…
Towards a three-dimensional distribution of the molecular clouds in the Galactic Centre
Qing-Zeng Yan, A. J. Walsh, J. R. Dawson +8
We present a study of the three-dimensional structure of the molecular clouds in the Galactic Centre (GC) using CO emission and OH absorption lines. Two CO isotopologue lines, $^{1…
Molecular Lines of 13 Galactic Infrared Bubble Regions
Qing-zeng Yan, Ye Xu, Bo Zhang +3
We investigated the physical properties of molecular clouds and star formation processes around infrared bubbles which are essentially expanding HII regions. We performed observati…
The local spiral structure of the Milky Way
Ye Xu, Mark Reid, Thomas Dame +7
The nature of the spiral structure of the Milky Way has long been debated. Only in the last decade have astronomers been able to accurately measure distances to a substantial numbe…
The Bar and Spiral Structure Legacy (BeSSeL) Survey: Mapping the Milky Way with VLBI Astrometry
Andreas Brunthaler, Mark J. Reid, Karl M. Menten +14
Astrometric Very Long Baseline Interferometry (VLBI) observations of maser sources in the Milky Way are used to map the spiral structure of our Galaxy and to determine fundamental…
