Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Tracing the Evolution of SMBHs and Stellar Objects in Galaxy Mergers: A Multi-mass Direct N-body Model
星系合并 SMBH 恒星物体演化 多质量 直接N体模型
2023/11/13
By using direct N-body numerical simulations, we model the dynamical coevolution of two supermassive black holes (SMBHs) and the surrounding stars in merging galaxies. In order to investigate how diff...
The bar-halo interaction - II. Secular evolution and the religion of N-body simulations
stellar dynamics dark matter
2014/12/23
This paper explores resonance-driven secular evolution between a bar and dark matter halo using N-body simulations. We make direct comparisons to our analytic theory to demonstrate the great difficult...
The bar-halo interaction - I. From fundamental dynamics to revised N-body requirements
dark matter formation

A galaxy remains near equilibrium for most of its history. Only through resonances can non-axisymmetric features, such as spiral arms and bars, exert torques over large scales and change the overall s...
The secular approximation for the evolution of hierarchical triple configurations has proven to be very useful in many astrophysical contexts, from planetary to triple-star systems. In this approximat...

TreePM：A Code for Cosmological N-Body Simulations
Gravitation methods numerical cosmology large scale structure of the universe
2009/5/19
We describe the TreePM method for carrying out large N-Body
simulations to study formation and evolution of the large scale structure in
the Universe. This method is a combination of Barnes and Hut ...
Effects of the Size of Cosmological N-body Simulations on Physical Quantities– II：Halo Formation and Destruction Rate
Large scale structure of Universe N-body simulations galaxies
2009/5/12
In this study we show how errors due to finite box size
affect formation and the destruction rate for haloes in cosmological N-body
simulations. In an earlier study we gave an analytic prescription ...
