Growth from KiDS: Stellar mass assembly of galaxies since z=2 in the light of Kilo-Degree Survey
Qingshan Wang, Antonios Katsianis, Nicola R. Napolitano +10
We measure the galaxy stellar mass function at using 28M galaxies from the KiDS DR4 which spans an effective survey area of 676.9 deg. Combining nine-band photometry…
ELUCID-DESI II. Revealing dark matter mass, tidal, and velocity (MTV) fields using galaxy group phase information
Qingyang Li, Xiaohu Yang, Wensheng Hong +24
We introduce a novel method for reconstructing the cosmic mass, tidal, and velocity (MTV) fields over the redshift range using the phase information of galaxy groups.…
A semi-analytical mock galaxy catalog for the CSST extragalactic surveys from the Jiutian simulations
Zhenlin Tan, Lizhi Xie, Jiaxin Han +17
We introduce a mock galaxy catalog built for the CSST extragalactic surveys using the primary runs of the Jiutian -body simulation suites. The catalogs are built by coupling the…
The Jiutian simulations for the CSST extra-galactic surveys
Jiaxin Han, Ming Li, Wenkang Jiang +23
We provide an overview of the Jiutian simulations, a hybrid simulation suite for the China Space Survey Telescope (CSST) extragalactic surveys. It consists of four complementary mo…
Photometric Objects Around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. VIII. Revisiting the Lensing is Low Effect
Xiaolin Luo, Kun Xu, Yipeng Jing +6
The issue of over-predicting the galaxy-galaxy lensing (GGL) signal using conventional galaxy-halo connection models has become well-known as the ``Lensing is Low'' problem, which…
Self-similar decomposition of the hierarchical merger tree of dark matter halos
Wenkang Jiang, Jiaxin Han, Fuyu Dong +1
In the CDM universe, structure formation is generally not a self-similar process, while some self-similarity remains in certain statistics which can greatly simplify our descrip…
CSST Cosmological Emulator I: Matter Power Spectrum Emulation with one percent accuracy to k = 10 h/Mpc
Zhao Chen, Yu Yu, Jiaxin Han +1
In the near future, the China Space Station Telescope (CSST) will obtain unprecedented imaging and spectroscopic data. The statistical errors in the cosmological parameter constrai…
DarkAI: Reconstructing the density, velocity and tidal field of dark matter from a DESI-like bright galaxy sample
Feng Shi, Zitong Wang, Xiaohu Yang +10
Reconstructing the mass density, velocity, and tidal (MTV) fields of dark matter from galaxy surveys is essential for advancing our understanding of the LSS of the Universe. In thi…
Einasto profile as the halo model solution coupled to the depletion radius
Yifeng Zhou, Jiaxin Han
We constrain the halo profiles outside the halo boundaries by solving for the matching profiles required by the halo model. In the halo model framework, the matter distribution in…
Simulating emission line galaxies for the next generation of large-scale structure surveys
Wenxiang Pei, Qi Guo, Ming Li +8
We investigate emission line galaxies across cosmic time by combining the modified L-Galaxies semi-analytical galaxy formation model with the JiuTian cosmological simulation. We im…
JWST's first glimpse of a z > 2 forming cluster reveals a top-heavy stellar mass function
Hanwen Sun, Tao Wang, Ke Xu +11
Clusters and their progenitors (protoclusters) at z = 2-4, the peak epoch of star formation, are ideal laboratories to study the formation process of both the clusters themselves a…
Cosmological Forecast of the Void Size Function Measurement from the CSST Spectroscopic Survey
Yingxiao Song, Qi Xiong, Yan Gong +11
Void size function (VSF) contains information of the cosmic large-scale structure (LSS), and can be used to derive the properties of dark energy and dark matter. We predict the VSF…
PAC.V. The Roles of Mass and Environment in the Quenching of Galaxies
Yun Zheng, Kun Xu, Y. P. Jing +6
The roles that mass and environment play in the galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs (PAC) method, we analyze the excess s…
The history and mass content of cluster galaxies in the EAGLE simulation
Cristóbal Sifón, Jiaxin Han
We explore the mass content of galaxies residing in galaxy clusters at z=0 in the EAGLE hydrodynamical simulation as well as the galaxies' mass build-up through cosmic time. We use…
StarGO: A New Method to Identify the Galactic Origins of Halo Stars
Zhen Yuan, Jiang Chang, Projjwal Banerjee +3
We develop a new method StarGO (Stars' Galactic Origin) to identify the galactic origins of halo stars using their kinematics. Our method is based on self-organizing map (SOM), whi…
Resolving Subhaloes' Lives with the Hierarchical Bound-Tracing Algorithm
Jiaxin Han, Y. P. Jing, Huiyuan Wang +1
We develop a new code, the Hierarchical Bound-Tracing (HBT for short) code, to find and trace dark matter subhaloes in simulations based on the merger hierarchy of dark matter halo…
