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...

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...

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...
