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…
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…
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…
Measuring the X-ray luminosities of DESI groups from eROSITA Final Equatorial-Depth Survey: I. X-ray luminosity -- halo mass scaling relation
Yunliang Zheng, Xiaohu Yang, Min He +3
We use the eROSITA Final Equatorial-Depth Survey (eFEDS) to measure the rest-frame 0.1-2.4 keV band X-ray luminosities of 600,000 DESI groups using two different algorithms…
The Three Hundred Project: the evolution of physical baryon profiles
Qingyang Li, Weiguang Cui, Xiaohu Yang +7
The distribution of baryons provides a significant way to understand the formation of galaxy clusters by revealing the details of its internal structure and changes over time. In t…
Late-formed halos prefer to host quiescent central galaxies. I. Observational results
Kai Wang, Yangyao Chen, Qingyang Li +1
The star formation and quenching of central galaxies are regulated by the assembly histories of their host halos. In this work, we use the central stellar mass to halo mass ratio a…
\textsc{The Three Hundred} project: The \textsc{Gizmo-Simba} run
Weiguang Cui, Romeel Dave, Alexander Knebe +22
We introduce \textsc{Gizmo-Simba}, a new suite of galaxy cluster simulations within \textsc{The Three Hundred} project. \textsc{The Three Hundred} consists of zoom re-simulations o…
A machine learning approach to infer the accreted stellar mass fractions of central galaxies in the TNG100 simulation
Rui Shi, Wenting Wang, Zhaozhou Li +5
We propose a random forest (RF) machine learning approach to determine the accreted stellar mass fractions () of central galaxies, based on various dark matter halo…
What to expect from dynamical modelling of cluster haloes I. The information content of different dynamical tracers
Qingyang Li, Jiaxin Han, Wenting Wang +3
Using hydrodynamical simulations, we study how well the underlying gravitational potential of a galaxy cluster can be modelled dynamically with different types of tracers. In order…
An Extended Halo-based Group/Cluster finder: application to the DESI legacy imaging surveys DR8
Xiaohu Yang, Haojie Xu, Min He +20
We extend the halo-based group finder developed by \citet[][]{Yang2005a} to use data {\it simultaneously} with either photometric or spectroscopic redshifts. A mock galaxy redshift…
The Three Hundred Project: the stellar and gas profiles
Qingyang Li, Weiguang Cui, Xiaohu Yang +7
Using the catalogues of galaxy clusters from The Three Hundred project, modelled with both hydrodynamic simulations, (Gadget-X and Gadget-MUSIC), and semi-analytic models (SAMs), w…
