Star Proper Motions Based on Two-epoch Observations from the SDSS and DESI Imaging Surveys
Yun-Ao Xiao, Hu Zou, Xin Xu +9
In this study, we present the construction of a new proper motion catalog utilizing the photometric data from the Sloan Digital Sky Survey (SDSS) and Dark Energy Spectroscopic Inst…
Photometric redshifts and Galaxy Clusters for DES DR2, DESI DR9, and HSC-SSP PDR3 Data
Hu Zou, Jipeng Sui, Suijian Xue +8
Photometric redshift (photo-z) is a fundamental parameter for multi-wavelength photometric surveys, while galaxy clusters are important cosmological probers and ideal objects for e…
Short term minutes-time scale temporal variation statistics of sodium layer dynamics
Lu Feng, Kai Jin, Hong-Yang Li +10
The brightness and height of the sodium laser guide star of adaptive optics could vary significantly due to the temporal dynamics of sodium column density and the mean height of so…
Numerical study of a 20W class QCW pulsed sodium guide star laser's performances at five sites in China
Hongyang Li, Lu Feng, Junwei Zuo +6
In the past few years, Chinese astronomical community is actively testing astronomical sites for several new optical/infrared ground-based telescopes. These site testing campaigns…
Site testing campaign for the Large Optical/infrared Telescope of China: Overview
Lu Feng, Jin-Xin Hao, Zi-Huang Cao +35
The Large Optical/infrared Telescope (LOT) is a ground-based 12m diameter optical/infrared telescope which is proposed to be built in the western part of China in the next decade.…
Optical turbulence at Ali, China -- Results from the first year of lunar scintillometer observations
Paul Hickson, Lu Feng, Joschua A. Hellemeier +6
The location of an astronomical observatory is a key factor that affects its scientific productivity. The best astronomical sites are generally those found at high altitudes. Sever…
Modulation of Galactic Cosmic Rays in the Inner Heliosphere over Solar Cycles
Z. -N. Shen, G. Qin
The 11-year and 22-year modulation of galactic cosmic rays (GCRs) in the inner heliosphere are studied using a numerical model developed by Qin and Shen in 2017. Based on the numer…
A Sodium laser guide star coupling efficiency measurement method
Feng Lu, Zhi-Xia Shen, Suijian Xue +8
Large telescope's adaptive optics (AO) system requires one or several bright artificial laser guide stars to improve its sky coverage. The recent advent of high power sodium laser…
Multi-waveband polarimetric observations of NRAO 530 on parsec-scale
Y. J. Chen, Z. -Q. Shen, S. -W. Feng
We report on multi-bands VLBA polarimetric observations of NRAO 530 in February 1997. Total intensity, EVPA distributions at all these frequencies are presented. Model fitting has…
Lithium and proton-capture elements in Globular Cluster dwarfs: the case of 47 Tuc
Valentina D'Orazi, Sara Lucatello, Raffaele Gratton +5
Previous surveys in a few metal-poor globular clusters (GCs) showed that the determination of abundances for Li and proton-capture elements offers a key tool to address the intracl…
