Comparative analysis of missing data imputation methods for CSST survey: Impact on photometric redshift estimation performance
Ling Wang, Zhu Chen, Zhijian Luo +42
Improving the accuracy of photometric redshifts (photo-) is essential for reliable statistical studies of cosmology and galaxy evolution. However, missing photometric bands are…
A Multi-modal Fusion Network for Star-Galaxy Classification from CSST Simulated Datasets
Zhuoming Han, Tianmeng Zhang, Chao Liu +1
The distinction between stars and galaxies is a fundamental problem in the field of celestial classification. This issue has become challenging for these ongoing and upcoming digit…
Cosmic Ray Detection and Rejection for CSST
Yan Yu, Bin Ma, Tianmeng Zhang +2
As a space telescope, the China Space Station Survey Telescope (CSST) will face significant challenges from cosmic ray (CR) contamination. These CRs will severely degrade image qua…
CSST Strong Lensing Preparation: a Framework for Detecting Strong Lenses in the Multi-color Imaging Survey by the China Survey Space Telescope (CSST)
Xu Li, Ruiqi Sun, Jiameng Lv +29
Strong gravitational lensing is a powerful tool for investigating dark matter and dark energy properties. With the advent of large-scale sky surveys, we can discover strong lensing…
A spectral data release for 104 Type II Supernovae from the Tsinghua Supernova Group
Han Lin, Xiaofeng Wang, Jujia Zhang +33
We present 206 unpublished optical spectra of 104 type II supernovae obtained by the Xinglong 2.16m telescope and Lijiang 2.4m telescope during the period from 2011 to 2018, spanni…
Discovery of the Closest Ultrastripped Supernova: SN 2021agco in UGC 3855
Shengyu Yan, Xiaofeng Wang, Xing Gao +16
We present the discovery and studies of the helium-rich, fast-evolving supernova (SN) 2021agco at a distance of 40 Mpc. Its early-time flux is found to rise from half peak t…
