Numerical cosmology on the GPU with Enzo and Ramses
Claudio Gheller, Peng Wang, Franco Vazza +1
A number of scientific numerical codes can currently exploit GPUs with remarkable performance. In astrophysics, Enzo and Ramses are prime examples of such applications. The two cod…
Two-particle correlations in a dynamic cluster approximation with continuous momentum dependence: Superconductivity in the 2D Hubbard model
Peter Staar, Thomas Maier, Thomas Schulthess
The DCA algortihm was recently introduced to extend the dynamic cluster approximation (DCA) with a continuous lattice self-energy in order to achieve better convergence with cl…
Simulations of cosmic rays in large-scale structures: numerical and physical effects
Franco Vazza, Claudio Gheller, Marcus Brüggen
Non-thermal (relativistic) particles are injected into the cosmos by structure formation shock waves, active galactic nuclei and stellar explosions. We present a suite of unigrid c…
Supersonic turbulence in 3D isothermal flow collision
Doris Folini, Rolf Walder, Jean M. Favre
Colliding supersonic bulk flows shape observable properties and internal physics of various astrophysical objects, like O-star winds, molecular clouds, galactic sheets, binaries, o…
