Sciences with the 2.5-meter Wide Field Survey Telescope (WFST)
WFST Collaboration, Tinggui Wang, Guilin Liu +60
The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying facility being built jointly by the University of Science and Technology of China and the Purple Mountai…
Photometric redshift estimation of galaxies in the DESI Legacy Imaging Surveys
Changhua Li, Yanxia Zhang, Chenzhou Cui +14
The accurate estimation of photometric redshifts plays a crucial role in accomplishing science objectives of the large survey projects. The template-fitting and machine learning ar…
Antarctic Survey Telescope 3-3: Overview, System Performance and Preliminary Observations at Yaoan, Yunnan
Tianrui Sun, Xiaoyan Li, Lei Hu +17
The third Antarctic Survey Telescope array instrument at Dome A in Antarctica, the AST3-3 telescope, has been in commissioning from March 2021. We deployed AST3-3 at the Yaoan astr…
A Systematic Analysis of Stellar Populations in the Host Galaxies of Changing-look AGNs
Jun-Jie Jin, Xue-Bing Wu, Xiao-Tong Feng
"Changing-look" active galactic nuclei (CL-AGNs) are a newly-discovered class of AGNs that show the appearance (or disappearance) of broad emission lines within a short time scale…
The LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap I. The Spectroscopic Redshift Catalog
Ming Yang, Hong Wu, Fan Yang +29
We present a spectroscopic redshift catalog from the LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap (SGC), which is designed to obse…
Spectral Identification of the u-band Variable Sources in Two LAMOST fields
TianWen Cao, Ming Yang, Hong Wu +17
We selected 82 u-band variable objects based on the u-band photometry data from SCUSS and SDSS, in the field of LAMOST Complete Spectroscopic Survey of Pointing Area at Southern Ga…
Photometry of Variable Stars from THU-NAOC Transient Survey I: The First 2 Years
Xinyu Yao, Lingzhi Wang, Xiaofeng Wang +9
In this paper, we report the detections of stellar variabilities from the first 2-year observations of sky area of about 1300 square degrees from the Tsinghua University-NAOC Trans…
Capability of Quasar Selection by Combining the SCUSS and SDSS Observations
Hu Zou, Xue-bing Wu, Xu Zhou +15
The South Galactic Cap -band Sky Survey (SCUSS) provides a deep -band imaging of about 5000 deg in south Galactic cap. It is about 1.5 mag deeper than the SDSS -band.…
Estimating Photometric Redshifts of Quasars via K-nearest Neighbor Approach Based on Large Survey Databases
Zhang Yanxia, Ma He, Peng Nanbo +2
We apply one of lazy learning methods named k-nearest neighbor algorithm (kNN) to estimate the photometric redshifts of quasars, based on various datasets from the Sloan Digital Sk…
