Galaxy merger statistics and inferred bulge-to-disk ratios in cosmological SPH simulations
formation spiral elliptical
2014/12/24
We construct merger trees for galaxies identified in a cosmological hydrodynamic simulation and use them to characterize predicted merger rates as a function of redshift, galaxy mass, and merger mass ...
Accretion, feedback and galaxy bimodality: a comparison of the GalICS semi-analytic model and cosmological SPH simulations
cooling fl ows evolution
2014/12/23
We compare the galaxy population of a smoothed particle hydrodynamics (SPH) simulation to those predicted by the GalICS (Galaxies In Cosmological Simulations) N-body + semi-analytic model and a stripp...

2014/12/9
We explore the growth of galaxies formed in self-consistent Smoothed Particle Hydrodynamic (SPH) cosmological simulations. In the first Chapter, we examine the temperature history of gas accreted by f...
The impact of numerical viscosity in SPH simulations of galaxy clusters
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/6
A SPH code employing a time-dependent artificial viscosity scheme is used to construct a large set of N-body/SPH cluster simulations for studying the impact of artificial viscosity on the thermodynami...
Sph simulations of early and late superhumps。
3D sph simulations of giant herbig-haro flows and jet-cloud interactions in star formation regions
smoothed particle hydro-dynamics star formation regions
2009/6/4
We review some recent results of three-dimensional smoothed particle hydro-dynamics (SPH) simulations of overdense, radiatively cooling jets in star formingregions. We discuss the structure and kinema...
