The Mixing and Transport Properties of the Simulated ICM: a Study with Tracers (2009)
Vazza, F., Gheller, C., Brunetti, G.
We present a study of the mixing properties of the simulated Intra Cluster Medium, using tracers particles that are advected by the gas flow during the evolution of cosmic structures. Using a sample...
Turbulent Motions and Shocks Waves in Galaxy Clusters simulated with AMR (2009)
Vazza, F., Brunetti, G., Kritsuk, A., Wagner, R., Gheller, C., Norman, M .
We have implemented an Adaptive Mesh Refinement criterion explicitly designed to increase spatial resolution around discontinuities in the velocity field in ENZO cosmological simulations. With this...
Vazza, F., Brunetti, G., Gheller, C.
We analyze the properties of Large Scale Shocks in a cosmological volume of size 103Mpc/h simulated with the public 1.0.1 release of the ENZO code. Different methods to identify and characterize...
Cosmological Shocks in Eulerian Simulations: Main Properties and Cosmic Rays Acceleration (2008)
Vazza, F., Brunetti, G., Gheller, C.
Aims: morpholgies, number and energy distributions of Cosmological Shock Waves from a set of ENZO cosmological simulations are produced, along with a study of the connection with Cosmic Rays...
Turbulent Velocity Fields in SPH--simulated Galaxy Clusters (2006)
Vazza, F., Tormen, G., Cassano, R., Brunetti, G., Dolag, K.
We present a study of the turbulent velocity fields in the Intra Cluster Medium of a sample of 21 galaxy clusters simulated by the SPH--code Gadget2, using a new numerical scheme where the artificial...
Turbulent gas motions in galaxy cluster simulations: The role of SPH viscosity (2005)
Dolag, K., Vazza, F., Brunetti, G., Tormen, G.
Smoothed particle hydrodynamics (SPH) employs an artificial viscosity to properly capture hydrodynamical shock waves. In its original formulation, the resulting numerical viscosity is large enough to...
