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...
Direct N-body Simulations of Rubble Pile Collisions
asteroids collisional physics impact processes planetary formation planetesimals
2015/12/25
There is increasing evidence that many kilometer-sized bodies in the Solar System are piles of rubble bound together by gravity. We present results from a project to map the parameter space of collisi...
Direct Large-Scale N-Body Simulations of Planetesimal Dynamics
N-body simulation planetesimals planetary formation planetary dynamics resonances
2015/12/25
We describe a new direct numerical method for simulating planetesimal dynamics in which N ～ 106 or more bodies can be evolved simultaneously in three spatial dimensions over hundreds ofdynamical times...
The Energy Spectrum of Telescope Array's Middle Drum Detector and the Direct Comparison to the High Resolution Fly's Eye Experiment
UHECR cosmic ray Telescope Array energy spectrum High Resolution Fly’s Eye monocular hybrid HiRes
2012/2/24
The Telescope Array's Middle Drum fluorescence detector was instrumented with telescopes refurbished from the High Resolution Fly's Eye's HiRes-1 site. The data observed by Middle Drum in monocular mo...

Dipole Collapse Dynamo Waves Global Direct Numerical Simulations
2012/2/23
Magnetic fields of low-mass stars and planets are thought to originate from self-excited dynamo action in their convective interiors. Observations reveal a variety of field topologies ranging from lar...

Fine-Tuning Implications Direct Dark Matter Searches
2011/10/14
We study theoretical implications of direct dark matter searches in the minimal supersymmetric standard model (MSSM). We assume that no accidental cancellations occur in the spin-independent elastic n...

2011/1/13
EDELWEISS-2 is a Ge-bolometer experiment located in the underground laboratory Laboratoire Souterrain de Modane (LSM, France). For the second phase of the experiment, the collaboration has developed n...
Prospects for Direct Detection of Inflationary Gravitational Waves by Next Generation Interferometric Detectors
Direct Detection Inflationary Gravitational Waves Next Generation Interferometric Detectors
2011/1/11
We study the potential impact of detecting the inflationary gravitational wave background by the future space-based gravitational wave detectors, such as DECIGO and BBO. The signal-to-noise ratio of e...
The First Galaxies: Assembly of Disks and Prospects for Direct Detection
cosmology observations galaxies formation galaxies
2010/11/9
The James Webb Space Telescope (JWST) will enable observations of galaxies at redshifts z & 10 and hence allow to test our current understanding of structure formation at very early times. Previous wo...
Direct N-body simulations of globular clusters: (I) Palomar 14
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
We present the first ever direct $N$-body computations of an old Milky Way globular cluster over its entire life time on a star-by-star basis. Using recent GPU hardware at Bonn University, we have per...
