The shape-velocity alignment of satellites forged by tidal locking and dynamical friction
Hao Yang, Wenting Wang, Ting S. Li +8
Utilizing the TNG50 simulation, we study two types of alignments for satellites/subhalos: 1) the alignment of their major axes with the galactocentric radial directions (radial ali…
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…
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…
