Black holes make for a great space mystery. They're so massive that nothing, not even light, can escape a black hole once it gets close enough. A great mystery for scientists is that there's evidence ...
An implementation of the soft-sphere discrete element method in a high-performance parallel gravity tree-code
Bulk solids Solar system DEM Hopper SSDEM
2015/12/25
We present our implementation of the soft-sphere discrete element method (SSDEM) in the parallel gravitational N-body code pkdgrav, a well-tested simulation package that has been used to provide many ...
A spectral code for non-equilibrium plasma and its applications
Spectrum Nonequilibrium plasma The program code
2014/12/9
The spectral code for non-equilibrium plasma has been developed based on the updated atomic database. The first application is for winds from super stellar clusters for which a self-consistent physica...
Mass segregation and fractal substructure in young massive clusters: (I) the McLuster code and method calibration

2011/10/8
By analysing models of the young massive cluster R136 in 30 Doradus, set-up using the herewith introduced and publicly made available code McLuster, we investigate and compare different methods for de...
N-body Simulations for f(R) Gravity using a Self-adaptive Particle-Mesh Code
N-body Simulations Self-adaptive Particle-Mesh Code
2010/11/11
We perform high resolution N-body simulations for f(R) gravity based on a self-adaptive particle-mesh code MLAPM. The Chameleon mechanism that recovers General Relativity on small scales is fully take...

GRMHD in axisymmetric dynamical spacetimes: the X-ECHO code
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
We present a new numerical code, X-ECHO, for general relativistic magnetohydrodynamics (GRMHD) in dynamical spacetimes. This is aimed at studying astrophysical situations where strong gravity and magn...
