CUBE2: A Parallel -Body Simulation Code for Scalability, Accuracy, and Memory Efficiency
Hao-Ran Yu, Bing-Hang Chen, Kun Xu +4
-body simulation serves as a critical method for modeling cosmic evolution and poses a significant challenge in high-performance computing. We present CUBE2, an open-source cosm…
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…
Luminosity and stellar mass functions of faint photometric satellites around spectroscopic central galaxies from DESI Year-1 Bright Galaxy Survey
Wenting Wang, Xiaohu Yang, Yipeng Jing +47
We measure the luminosity functions (LFs) and stellar mass functions (SMFs) of photometric satellite galaxies around spectroscopically identified isolated central galaxies (ICGs).…
PAC in DESI. I. Galaxy Stellar Mass Function into the Frontier
Kun Xu, Y. P. Jing, Shaun Cole +34
The Photometric Objects Around Cosmic Webs (PAC) method integrates cosmological photometric and spectroscopic surveys, offering valuable insights into galaxy formation. PAC measure…
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…
