Weak Evolution of Cosmic Atomic Hydrogen over the Past 4.5 Billion Years
Chuan-Peng Zhang, Hong Guo, Yizhou Gu +49
The cosmic star formation rate density (CSFRD) has declined sharply toward the present day, but the roles of the atomic and molecular gas reservoirs remain uncertain. We measure th…
X-ray variability of SDSS J000532.84+200717.4: from a normal state to an X-weak state
Xiaohui Yang, Yanli Ai, Liming Dou +8
We present a multi-epoch study of the extreme X-ray variability of the type~1 quasar SDSS~J000532.84+200717.4 using archival observations from \textit{XMM-Newton}, \textit{Swift}/X…
Probing Large-scale Structure and the Multi-Phase IGM at the Cosmic Noon -- Insights from a Joint Survey with Euclid, CSST, JPCam, and JUST
Jiang-Tao Li, Renato A. Dupke, Yan Gong +4
We present scientific and technical justifications of a potential coordinated Euclid/CSST/JPCam/JUST survey of the Euclid Deep Field North (EDF-N), aimed at probing the multi-phase…
Direct Measurement of Galaxy Assembly Bias using DESI DR1 Data
Zhiwei Shao, Ying Zu, Andrés N. Salcedo +54
We report the first direct measurement of galaxy assembly bias, a critical systematic in cosmology, from the Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey. We in…
The mass and redshift dependence of halo star clustering
Zhenlin Tan, Wenting Wang, Jiaxin He +5
We adopt the two point correlation function (2PCF) as a statistical tool to quantify the spatial clustering of halo stars, for galaxy systems spanning a wide range in host halo vir…
Establishing HI mass v.s. stellar mass and halo mass scaling relations using an abundance matching method
Yi Lu, Xiaohu Yang, Chengze Liu +5
We combined data from the Sloan Digital Sky Survey (SDSS) and the Arecibo Legacy Fast ALFA Survey (ALFALFA) to establish the HI mass vs. stellar mass and halo mass scaling relation…
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…
The conditional colour-magnitude distribution: II. A comparison of galaxy colour and luminosity distribution in galaxy groups
Haojie Xu, Zheng Zheng, Xiaohu Yang +2
The Conditional Colour-Magnitude Distribution (CCMD) is a comprehensive formalism of the colour-magnitude-halo mass relation of galaxies. With joint modelling of a large sample of…
Using two point correlation functions to understand the assembly histories of Milky Way-like galaxies
Yike Zhang, Wenting Wang, Jiaxin Han +4
The two point correlation function (2PCF) is a powerful statistical tool to measure galaxy clustering. Although 2PCF has also been used to study the clustering of stars on parsec a…
