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...

Cosmology Dark energy Thermodynamics
2011/10/13
The thermodynamic and dynamical properties of a variable dark energy model with density scaling as rho_x \propto (1+z)^m, z being the redshift, are discussed following the outline of Jetzer et al. Thi...
