Galaxy Clusters from the DESI Legacy Imaging Surveys. IV. Alignment of Member Galaxy Orientations at z < 0.5
Zhaobin Chen, Yizhou Gu, Shufei Liu +2
Using DESI photometric catalog data, we systematically analyze the spatial alignment of star-forming galaxies (SFGs) and quiescent galaxies (QGs) in clusters. The results reveal th…
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…
Galaxy clusters from the DESI Legacy Imaging Surveys -- III. Star-forming fraction of brightest cluster galaxies
Shufei Liu, Hu Zou, Jinfu Gou +10
This study investigates the evolution of the star-forming fraction () of Brightest Cluster Galaxies (BCGs) at , using the galaxy clusters identified from th…
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…
Estimating Photometric Redshifts for Galaxies from the DESI Legacy Imaging Surveys with Bayesian Neural Networks Trained by DESI EDR
Xingchen Zhou, Nan Li, Hu Zou +6
We present a catalogue of photometric redshifts for galaxies from DESI Legacy Imaging Surveys, which includes billion sources covering 14,000 . The photomet…
Accurately Estimating Redshifts from CSST Slitless Spectroscopic Survey using Deep Learning
Xingchen Zhou, Yan Gong, Xin Zhang +10
Chinese Space Station Telescope (CSST) has the capability to conduct slitless spectroscopic survey simultaneously with photometric survey. The spectroscopic survey will measure sli…
Probing the cosmic web in Ly emission over large scales: an Intensity Mapping forecast for DECaLS/BASS and DESI
Pablo Renard, Daniele Spinoso, Zechang Sun +3
Being the most prominent HI line, Ly permeates the cosmic web in emission. Despite its potential as a cosmological probe, its detection on large scales remains elusive. We prese…
CSST large-scale structure analysis pipeline: I. constructing reference mock galaxy redshift surveys
Yizhou Gu, Xiaohu Yang, Jiaxin Han +29
In this paper, we set out to construct a set of reference mock galaxy redshift surveys (MGRSs) for the future Chinese Space-station Survey Telescope (CSST) observation, where subse…
CSST Large-scale Structure Analysis Pipeline: II. the CSST Emulator for Slitless Spectroscopy (CESS)
Run Wen, Xian Zhong Zheng, Yunkun Han +9
The Chinese Space Station Telescope (CSST) slitless spectroscopic survey will observe objects to a limiting magnitude of ~ 23 mag (5, point sources) in U, V, and I over 17500 de…
Galaxy Clusters from the DESI Legacy Imaging Surveys.II. Environment effects on size-mass relation
Zhaobin Chen, Yizhou Gu, Hu Zou +1
To investigate the environment effects on size growth of galaxies, we study the size-mass relation across a broad range of environment with a vast sample of approximately 32 millio…
Measuring the conditional luminosity and stellar mass functions of galaxies by combining the DESI LS DR9, SV3 and Y1 data
Yirong Wang, Xiaohu Yang, Yizhou Gu +42
In this investigation, we leverage the combination of Dark Energy Spectroscopic Instrument Legacy imaging Surveys Data Release 9 (DESI LS DR9), Survey Validation 3 (SV3), and Year…
