Voids in the distribution of galaxies and the Cosmological constant
Roland Triay, Henri-Hugues Fliche
With the motivation in mind to evaluate the contribution of the cosmological constant on the foam like patterns formation process in the distribution of galaxies, we investigat…
Euler-Poisson-Newton approach in Cosmology
Roland Triay, Henri-Hugues Fliche
This lecture provides us with Newtonian approaches for the interpretation of two puzzling cosmological observations that are still discussed subject : a bulk flow and a foam like s…
Spherical Voids in Newton-Friedmann Universe
Roland Triay, Henri-Hugues Fliche
We show that the cosmological constant favours significantly the growth of voids in the universe. This dynamical effect is investigated within a newtonian approach with an extensio…
effect in the cosmological expansion of voids
Henri-Hugues Fliche, Roland Triay
The dynamical effect of the cosmological constant on a single spherical void evolving in a the universe is investigated within a non linear perturbation of Newton-Friedmann mod…
Anisotropic Hubble expansion of large scale structures
Henri-Hugues Fliche, Jean-Marie Souriau, Roland Triay
We investigate the dynamics of an homogenous distribution of galaxies moving under the cosmological expansion through Euler-Poisson equations system. The solutions are interpreted…
