Milky Way Mass Through Escape Velocity Curve from LAMOST K Giants
Yin Wu, Haining Li, Yang Huang +2
Escape velocity has long been used to constrain the mass of the Dark Matter (DM) halo in the Milky Way (MW). Here we present a study of the escape velocity curve using a sample of…
Identification of OB associations using the LAMOST-Gaia OB star sample
Zhicun Liu, Xiao-Long Wang, Wenyuan Cui +7
OB associations, as an intermediate stage between Galactic clusters and field stars, play an important role in understanding the star formation process, early stellar evolution, an…
Digitization of Astronomical Photographic Plate of China: Photometric Calibration of Single-exposure Plates and Release of Photometric Catalogs
Ma Mingyang, Yuan Haibo, Xiao Kai +15
The Chinese Plate-Digitizing Project has digitized a total number of about 30,000 astronomical plates from 11 telescopes of five observatories (SHAO, NAOC, PMO, YNAO, and QDO) in C…
The Mini-SiTian Array: Light Curves Analysis of Asteroids
Zhaoxing Liu, Jian Gao, Hongrui Gu +6
The SiTian project, with its vast field of view, will become an ideal platform for asteroid scientific research. In this study, we develop a pipeline to analyze the photometry of a…
The Mini-SiTian Array: real-bogus classification using deep learning
Jing-Hang Shi, Hong-Rui Gu, Yang Huang +2
The Mini-SiTian (MST) project is a pathfinder for China's next-generation large-scale time-domain survey, SiTian, aimed at discovering variable stars, transients, and explosive eve…
Finding Quasars Behind the Galactic Plane: Spectroscopic Identifications of ~1300 New Quasars at |b|<=20 degree from LAMOST DR10
Zhi-Ying Huo, Yuming Fu, Yang Huang +10
Quasars behind the Galactic plane (GPQs) are excellent tracers to probe the chemistry and kinematics of the interstellar/intergalactic medium (ISM/IGM) of the Milky Way along sight…
