The growth of central and satellite galaxies in cosmological smoothed particle hydrodynamics simulations
theory formation
2014/12/23
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7 × 109 M⊙. Most frien...
Testing Subhalo Abundance Matching in Cosmological Smoothed Particle Hydrodynamics Simulations

2014/12/22
Subhalo abundance matching (SHAM) is a technique for populating simulated dark matter distributions with galaxies, assuming a monotonic relation between a galaxy's stellar mass or luminosity and the m...
Feature-scale Simulations of Particulate Slurry Flows in Chemical Mechanical Polishing by Smoothed Particle Hydrodynamics

2012/2/29
We study and implement a simple method, based on the Perfectly Matched Layer approach, to treat non reflecting boundary conditions with the Smoothed Particles Hydrodynamics numerical algorithm. The me...
A Density Independent Formulation of Smoothed Particle Hydrodynamics
Density Independent Formulation Smoothed Particle Hydrodynamics Cosmology and Extragalactic Astrophysics
2012/2/21
In the standard formulation of the smoothed particle hydrodynamics (SPH), it is assumed that the local density distribution is differentiable. This assumption is used to derive the spatial derivatives...

2010/10/29
Molecular clouds have a hierarchical structure from few tens of
parsecs for giants to few tenth of a parsec for proto-stellar cores. Nowadays, our
observational techniques are so advanced that it ha...
