SPH-EXA: Enhancing the Scalability of SPH codes Via an Exascale-Ready SPH Mini-App
Danilo Guerrera, Aurélien Cavelan, Rubén M. Cabezón +6
Numerical simulations of fluids in astrophysics and computational fluid dynamics (CFD) are among the most computationally-demanding calculations, in terms of sustained floating-poi…
Towards a Mini-App for Smoothed Particle Hydrodynamics at Exascale
Danilo Guerrera, Rubén M. Cabezón, Jean-Guillaume Piccinali +5
The smoothed particle hydrodynamics (SPH) technique is a purely Lagrangian method, used in numerical simulations of fluids in astrophysics and computational fluid dynamics, among m…
DIAPHANE: a Portable Radiation Transport Library for Astrophysical Applications
Darren S. Reed, Tim Dykes, Ruben Cabezon +2
One of the most computationally demanding aspects of the hydrodynamical modelling of Astrophysical phenomena is the transport of energy by radiation or relativistic particles. Phys…
Hints against the cold and collisionless nature of dark matter from the galaxy velocity function
Aurel Schneider, Sebastian Trujillo-Gomez, Emmanouil Papastergis +2
The observed number of dwarf galaxies as a function of rotation velocity is significantly smaller than predicted by the standard model of cosmology. This discrepancy cannot be simp…
Another baryon miracle? Testing solutions to the "missing dwarfs" problem
Sebastian Trujillo-Gomez, Aurel Schneider, Emmanouil Papastergis +2
The dearth of dwarf galaxies in the local universe is hard to reconcile with the large number of low mass haloes expected within the concordance CDM paradigm. In this paper we p…
Matter power spectrum and the challenge of percent accuracy
Aurel Schneider, Romain Teyssier, Doug Potter +7
Future galaxy surveys require one percent precision in the theoretical knowledge of the power spectrum over a large range including very nonlinear scales. While this level of accur…
