Distributions and Physical Properties of Molecular Clouds in the Third Galactic Quadrant: = [219.75, 229.75] and = [-5.25, 5.25]
Yiwei Dong, Yan Sun, Ye Xu +11
We present the results of an unbiased CO/CO/CO ( = 1-0) survey in a portion of the third Galactic quadrant (TGQ): = [219.75, 229.75] and = […
Calibrating the Cepheid Period--Wesenheit Relation in the Gaia Bands using Galactic Open Cluster Cepheids
Zehao Lin, Ye Xu, Chaojie Hao +3
Establishing the period--Wesenheit relation requires independent and accurate distance measurements of classical Cepheids (DCEPs). The precise distance provided by an associated op…
The Effect of Light Deflection by Solar System Objects on High-Precision SKA Astrometry
Yingjie Li, Ye Xu, Shaibo Bian +4
We have computed the deflection angles caused by 195 objects in the solar system, including 177 satellites and eight asteroids. Twenty-one satellites and six asteroids can bend lig…
Local Spiral Structure Traced by Red Clump Stars
Zehao Lin, Ye Xu, Ligang Hou +5
Using the cross-matched data of Gaia EDR3 and the 2MASS Point Source Catalog, a sample of RC stars with parallax accuracies better than 20% is identified and used to reveal the nea…
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…
Three isotopologues CO survey of Molecular Clouds in the CMa OB1 complex
Ze-Hao Lin, Yan Sun, Ye Xu +2
Using the Purple Mountain Observatory 13.7-m millimeter telescope at Delingha in China, we have conducted a large-scale simultaneous survey of CO, CO, and \xxco (…
CO Outflow Candidates Toward the W3/4/5 Complex II: Feedback from Candidate Outflows
Yingjie Li, Ye Xu, Yan Sun +1
To date, few studies have focused on protostellar outflow feedback at scales larger than several parsecs. To address this paucity of research, we investigate the effects of feedbac…
Searching for Molecular Outflows with Support Vector Machines: Dark Cloud Complex in Cygnus
Shaobo Zhang, Ji Yang, Ye Xu +6
We present a survey of molecular outflows across the dark cloud complex in the Cygnus region, based on 46.75 deg^2 field of CO isotopologues data from Milky Way Imaging Scroll Pain…
The Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) Quasar Survey: Quasar Properties from Data Release Two and Three
X. Y. Dong, Xue-Bing Wu, Y. L. Ai +19
This is the second installment for the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) Quasar Survey, which includes quasars observed from September 2013 to June…
Molecular Gas Toward the Gemini OB1 Molecular Cloud Complex II: CO Outflow Candidates with Possible WISE Associations
Yingjie Li, Fa-Cheng Li, Ye Xu +4
We present a large scale survey of CO outflows in the Gem OB1 molecular cloud complex and its surroundings using the Purple Mountain Observatory Delingha 13.7 m telescope. A total…
A 95 GHz Methanol Emission Survey Toward Eight Small Supernova Remnants
Yingjie Li, Ye Xu, Xi Chen +4
We report on a 95 GHz ( A) methanol (CHOH) emission survey with the Purple Mountain Observatory Delingha 13.7 m telescope. Eight supernova remnants (SNRs) with a…
A New 95 GHz Methanol Maser Catalog: I. Data
Wenjin Yang, Ye Xu, Xi Chen +4
The Purple Mountain Observatory 13.7 m radio telescope has been used to search for 95 GHz (8--7A) class I methanol masers towards 1020 Bolocam Galactic Plane Survey (BG…
CO Core Candidates in the Gemini Molecular Cloud
Yingjie Li, Ye Xu, Ji Yang +3
We present observations of a 4 squared degree area toward the Gemini cloud obtained using J = 1-0 transitions of CO, CO and CO. No CO emission was detec…
