Dib, Sami, Walcher, C. Jakob, Heyer, Mark, Audit, Edouard, Loinard, Laurent
Supernova explosions inject a considerable amount of energy into the interstellar medium (ISM) in regions with high to moderate star formation rates. In order to assess whether driving of turbulence...
González, Matthias, Audit, Edouard, Stehlé, Chantal
Radiative shocks are found in various astrophysical objects and particularly at different stages of stellar evolution. Studying radiative shocks, their topology, and thermodynamical properties is...
Protostellar collapse: A comparison between SPH and AMR calculations (2008)
Commercon, Benoit, Hennebelle, Patrick, Audit, Edouard, Chabrier, Gilles, Teyssier, Romain
The development of parallel supercomputers allows today the detailed study of the collapse and the fragmentation of prestellar cores with increasingly accurate numerical simulations. Thanks to the...
The kinematic Sunyaev Zeldovich effect and transverse cluster velocities (1998)
Audit, Edouard, Simmons, John F. L.
The polarization of the CMBR scattered by galaxy clusters in the kinematic Sunyaev Zeldovich effect depends on the transverse velocity of the cluster. This polarizing effect is proportional to the...
The use of light polarization for weak-lensing inversions (1998)
Audit, Edouard, Simmons, John F. L.
The measurement of the integrated optical polarization of weakly gravitationally lensed galaxies can provide considerable constraints on lens models. The method outlined depends on fact that the...
Non-linear dynamics and mass function of cosmic structures. II Numerical results (1998)
Audit, Edouard, Teyssier, Romain, Alimi, Jean-Michel
We compare the mass functions obtained analytically, in the framework of an extended Press & Schechter (PS) formalism, in a previous paper to the numerical mass functions obtained in N -- body...
Non-linear Dynamics and Mass Function of Cosmic Structures: I Analytical Results (1997)
Audit, Edouard, Teyssier, Romain, Alimi, Jean-Michel
We investigate some modifications to the Press & Schechter (1974) (PS) prescription resulting from shear and tidal effects. These modifications rely on more realistic treatments of the collapse...
Gravitational Dynamics of Cold Matter using the Deformation Tensor (1996)
Audit, Edouard, Alimi, Jean-Michel
In this paper we present a new local Lagrangian approximation to the gravitational dynamics of cold matter. We describe the dynamics of a Lagrangian fluid element through only one quantity, the...
