The mass and structural evolution of massive galaxies is one of the hottest topics in galaxy formation. This is because it may reveal invaluable insights into the still debated evolutionary processes governing the growth and assembly of spheroids. Ho

Observations of colliding galaxy clusters with high relative velocity probe the tail of the halo pairwise velocity distribution with the potential of providing a powerful test of cosmology. As an example it has been argued that the discovery of the B

DEUS Full Observable {\Lambda}CDM Universe Simulation: the numerical challenge

Autor: Alimi, Jean-Michel, Bouillot, Vincent, Rasera, Yann, Reverdy, Vincent, Corasaniti, Pier-Stefano, Balmes, Irene, Requena, Stéphane, Delaruelle, Xavier, Richet, Jean-Noel

We have performed the first-ever numerical N- body simulation of the full observable universe (DEUS "Dark Energy Universe Simulation" FUR "Full Universe Run"). This has evolved 550 billion particles on an Adaptive Mesh Refinement grid with more than

International audience; The stellar mass-halo mass relation is a key constraint in all semi-analytic, numerical, and semi-empirical models of galaxy formation and evolution. However, its exact shape and redshift dependence remain under debate. Severa
