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…
Light Deflection under the Gravitational Field of Jupiter -- Testing General Relativity
Yingjie Li, Ye Xu, JingJing Li +6
We measured the relative positions between two pairs of compact extragalactic sources (CESs), J1925-2219 \& J1923-2104 (C1--C2) and J1925-2219 \& J1928-2035 (C1--C3) on 2020 Octobe…
Assessing the Performance of Molecular Gas Clump Identification Algorithms
Chong Li, Hong-chi Wang, Yuan-wei Wu +2
The detection of clumps(cores) in molecular clouds is an important issue in sub-millimetre astronomy. However, the completeness of the identification and the accuracy of the return…
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 spiral structure of the Milky Way
Ye Xu, Ligang Hou, Yuanwei Wu
The morphology and kinematics of the spiral structure of the Milky Way is a long-standing problem in astrophysics. In this review we firstly summarize various methods with differen…
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…
On the Relationship of UC H II Regions and Class II Methanol Masers: I. Source Catalogs
Bo Hu, Karl M. Menten, Yuanwei Wu +5
We conducted VLA C-configuration observations to measure positions and luminosities of Galactic Class II 6.7 GHz methanol masers and their associated ultra-compact H II regions. Th…
The East-Asian VLBI Network
Kiyoaki Wajima, Yoshiaki Hagiwara, Tao An +14
The East-Asian VLBI Network (EAVN) is the international VLBI facility in East Asia and is conducted in collaboration with China, Japan, and Korea. The EAVN consists of VLBI arrays…
CO observations of a sample towards nearby galaxies
Fa-Cheng Li, Yuan-Wei Wu, Ye Xu
We have simultaneously observed CO, CO, and CO (J=10) rotational transitions in the centers of a sample of 58 nearby spiral galaxies using the 13.7-m millim…
Herschel/HIFI observations of a new interstellar water maser: the 5(32)-4(41) transition at 620.701 GHz
David A. Neufeld, Yuanwei Wu, Alex Kraus +4
Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared (HIFI), we have performed mapping observations of the 620.701 GHz 5(32)-4(41) transition of ortho-…
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…
Multiwavelength study of low-luminosity 6.7-GHz methanol masers
Y. W. Wu, Y. Xu, J. Yang
We present results of 13CO(1-0), C18O(1-0), and HCO+(1-0) map observations and N2H+2 (1-0) single point observations directed towards a sample of nine low-luminosity 6.7-GHz masers…
A multiwavelength study of massive star-forming region IRAS 22506+5944
Yuan-Wei Wu, Ye Xu, Ji Yang +1
We present a multi-line study of the massive star-forming region IRAS 22506+5944. A new 6.7 GHz methanol maser was detected. 12CO, 13CO, C18O and HCO+ J = 1-0 transition observatio…
