Adaptive Refinement Tree: A New High-Resolution N-Body Code for Cosmological Simulations
Abstract : We present a new high-resolution N-body algorithm for cosmological simulations. The algorithm employs a traditional particle-mesh technique on a cubic grid and successive multilevel
The Santa Barbara cluster comparison project: A comparison of cosmological hydrodynamics solutions
We have simulated the formation of an X-ray cluster in a cold dark matter universe using 12 different codes. The codes span the range of numerical techniques and implementations currently in use,
Galaxies in N-Body Simulations: Overcoming the Overmerging Problem
We present analysis of the evolution of dark matter halos in dense environments of groups and clusters in dissipationless cosmological simulations. The premature destruction of halos in such
Spectropolarimetry of SN 2001el in NGC 1448: Asphericity of a Normal Type Ia Supernova*
High-quality spectropolarimetry (range 417-860 nm; spectral resolution 1.27 nm and 0.265 nm pixel-1) of the Type Ia supernova (SN Ia) 2001el was obtained with the ESO Very Large Telescope Melipal
Fully Threaded Tree Algorithms for Adaptive Refinement Fluid Dynamics Simulations
FTT is applied to the integration of the Euler equations of fluid dynamics and an adaptive-mesh time-stepping algorithm is described in which different time steps are used at different levels of the tree.
Three-dimensional Delayed-Detonation Model of Type Ia Supernovae
We study a Type Ia supernova explosion using large-scale three-dimensional numerical simulations based on reactive fluid dynamics with a simplified mechanism for nuclear reactions and energy release.
Hydrodynamical simulations of galaxy formation: effects of supernova feedback
We numerically simulate some of the most critical physical processes in galaxy formation: The supernova feedback, in conjunction with gasdynamics and gravity, plays a crucial role in determining how
Thermonuclear Supernovae: Simulations of the Deflagration Stage and Their Implications
Large-scale, three-dimensional numerical simulations of the deflagration stage of a thermonuclear supernova explosion show the formation and evolution of a highly convoluted turbulent flame in the
The structure of detonation waves in supernovae
La theorie de la detonation gazeuse est appliquee aux ondes de detonation thermonucleaires dans les supernovae. La structure des ondes de choc intenses est consideree dans un plasma degenere et
