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...
Splotch: Visualizing Cosmological Simulations (2008)
Dolag, K., Reinecke, M., Gheller, C., Imboden, S.
We present a light and fast, public available, ray-tracer {\tt Splotch} software tool which supports the effective visualization of cosmological simulations data. We describe the algorithm it relies...
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...
An Integrated Procedure for Tree-Nbody Simulations: FLY and AstroMD (2001)
Becciani, U., Antonuccio-Delogu, V., Buonomo, F., Gheller, C.
We present a code allowing to evolve three-dimensional self-gravitating collisionless systems with a large number of particles N >= 10^7. FLY (Fast Level-based N-bodY code) is a fully parallel code...
A Map-Making Algorithm for the Planck Surveyor (2001)
Natoli, P., De Gasperis, G., Gheller, C., Vittorio, N.
We present a parallel implementation of a map-making algorithm for CMB anisotropy experiments which is both fast and efficient. We show for the first time a Maximum Likelihood, minimum variance map...

Abstract. We present a parallel implementation of a map-making algorithm for CMB anisotropy experiments which is both fast and efficient. We show for the first time a Maximum Likelihood, minimum...
AstroMD. A multi-dimensional data analysis tool for astrophysical simulations (2000)
Becciani, U., Antonuccio-Delogu, V., Gheller, C., Calori, L., Buonomo, F., Imboden, S.
Over the past few years, the role of visualization for scientific purpose has grown up enormously. Astronomy makes an extended use of visualization techniques to analyze data, and scientific...
