We report the realization of the first cosmological simulations on the scale of the whole observable universe. These simulations have been carried out on 4752 nodes of the Curie supercomputer as a part of the Dark Energy Universe Simulation: Full Uni

Constraining AGN triggering mechanisms through the clustering analysis of active black holes

Publikováno v: Monthly Notices of the Royal Astronomical Society

The triggering mechanisms for Active Galactic Nuclei (AGN) are still debated. Some of the most popular ones include galaxy interactions (IT) and disk instabilities (DI). Using an advanced semi analytic model (SAM) of galaxy formation, coupled to accu

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 debated. Several recent works support a rela

Covariant Perturbations Theory in General Multi-Fluids Cosmology

Autor: Vincent Bouillot, Jean-Michel Alimi, Cristiano Germani

Publikováno v: Springer Proceedings in Physics ISBN: 9783319002965

We develop a variational approach, inspired by the work of Maldacena (Maldacena 2003, JHEP 0305), to study covariant cosmological perturbations in general multi-fluids extended gravity. A special attention is paid to the minimization of the propagati
