Multi-phase Hydrodynamics and X-ray Clusters Formation
Romain Teyssier, Jean-Pierre CHIEZE, Jean-Michel Alimi
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 hydrodyn…
Are Large X-ray Clusters at Thermal Equilibrium ?
Jean-Pierre Chieze, Romain Teyssier, Jean-Michel Alimi
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 poss…
Self Similar Spherical Collapse Revisited: a Comparison between Gas and Dark Matter Dynamics
Romain Teyssier, Jean-Pierre CHIEZE, Jean-Michel Alimi
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 a…
Gas and Dark Matter Spherical Dynamics
Jean-Pierre CHIEZE, Romain Teyssier, Jean-Michel Alimi
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 adiaba…
