MULTI-PHASE HYDRODYNAMICS AND X-RAY CLUSTERS FORMATION (2007)
Romain Teyssier, Jean-pierre Chieze
We investigate the role of radiative cooling within the core of large X-ray clusters using multi-phase hydrodynamics. We developed for that purpose a spherically symmetric hydrodynamical code,...
Non equilibrium thermodynamics and cosmological pancakes formation (1998)
Teyssier, Romain, Chieze, Jean-Pierre, Alimi, Jean-Michel
We investigate the influence of non equilibrium thermodynamics on cosmological structure formation. In this paper, we consider the collapse of planar perturbations usually called "Zel'dovich...
Multi-phase Hydrodynamics and X-ray Clusters Formation (1997)
Teyssier, Romain, CHIEZE, Jean-Pierre, Alimi, Jean-Michel
We investigate the role of radiative cooling within the core of large X-ray clusters using multi-phase hydrodynamics. We developed for that purpose a spherically symmetric hydrodynamical code,...
Are Large X-ray Clusters at Thermal Equilibrium ? (1997)
Chieze, Jean-Pierre, Teyssier, Romain, Alimi, Jean-Michel
We simulate the formation of a large X-ray cluster using a fully 3D hydrodynamical code coupled to a Particle-Mesh scheme which models the dark matter component. We focus on a possible decoupling...
Gas and Dark Matter Spherical Dynamics (1997)
CHIEZE, Jean-Pierre, Teyssier, Romain, Alimi, Jean-Michel
We investigate the formation of spherical cosmological structures following both dark matter and gas components. We focus on the dynamical aspect of the collapse assuming an adiabatic, $\gamma =...
Self Similar Spherical Collapse Revisited: a Comparison between Gas and Dark Matter Dynamics (1997)
Teyssier, Romain, CHIEZE, Jean-Pierre, Alimi, Jean-Michel
We reconsider the collapse of cosmic structures in an Einstein-de Sitter Universe, using the self similar initial conditions of Fillmore & Goldreich (1984). We first derive a new approximation to...
Serna, Arturo, Alimi, Jean-Michel, Chieze, Jean-Pierre
We present and test a general-purpose code, called PPASPH, for evolving self-gravitating fluids in astrophysics, both with and without a collisionless component. In PPASPH, hydrodynamical properties...
