Filtering Interlopers with Photometry and Diagnostic Features: A Machine Learning Framework Validated with CSST Slitless Spectroscopy
Hui Peng, Yu Yu, Yiyang Guo +13
The slitless spectroscopic method employed by missions such as Euclid and the Chinese Space-station Survey Telescope (CSST) faces a fundamental challenge: spectroscopic redshifts d…
Evolution of the Physical Properties of the Most Massive Galaxies in Clusters and their Protohalos
Qingyang Li, Xiaohu Yang, Antonios Katsianis +7
We investigated the evolution of the physical properties of the brightest galaxies in clusters and their protohalos from to . Galaxy clusters and groups are identifi…
Future Cosmology: New Physics and Opportunity from the China Space Station Telescope (CSST)
Yan Gong, Haitao Miao, Xingchen Zhou +12
The China Space Station Telescope (CSST) is the next-generation Stage~IV survey telescope. It can simultaneously perform multi-band imaging and slitless spectroscopic wide- and dee…
CSST Large Scale Structure Analysis Pipeline: III. Emission-line Redshift Measurement for Slitless Spectra
Jipeng Sui, Hu Zou, Xiaohu Yang +21
The China Space Station Telescope (CSST) is a forthcoming space-based optical telescope designed to co-orbit with the Chinese Space Station. With a planned slitless spectroscopic s…
From Halos to Galaxies. X: Decoding Galaxy SEDs with Physical Priors and Accurate Star Formation History Reconstruction
Zeyu Gao, Yingjie Peng, Kai Wang +18
The spectral energy distribution (SED) of galaxies is essential for deriving fundamental properties like stellar mass and star formation history (SFH). However, conventional method…
From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function
Dingyi Zhao, Yingjie Peng, Yipeng Jing +18
In CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM)…
