Breaking the cosmological invariance of the dark matter halos shape as a new probe of modified gravity

Remy Koskas, Jean-Michel Alimi

In a recent paper, Alimi & Koskas highlighted in CDM models derived from general relativity (GR) (with Dark Energy Universe numerical simulation data), a cosmological invariance…

The shape of dark matter halos: a new fundamental cosmological invariance

Jean-Michel Alimi, Remy Koskas

We focus on the complex relationship between the shape of dark matter halos and the cosmological models underlying their formation. We used three realistic cosmological models from…

Ray tracing the integrated Sachs-Wolfe effect through the light cones of the Dark Energy Universe Simulation -- Full Universe Runs

Julian Adamek, Yann Rasera, Pier Stefano Corasaniti +1

The late integrated Sachs-Wolfe (ISW) effect correlates the Cosmic Microwave Background (CMB) temperature anisotropies with foreground cosmic large-scale structures. As the correla…

Reconstructing matter profiles of spherically compensated cosmic regions in CDM cosmology

Paul de Fromont, Jean-Michel Alimi

The absence of a physically motivated model for large scale profiles of cosmic voids limits our ability to extract valuable cosmological information from their study. In this paper…

Probability distribution and statistical properties of spherically compensated cosmic regions in CDM cosmology

Jean-Michel Alimi, Paul de Fromont

The statistical properties of cosmic structures are well known to be strong probes for cosmology. In particular, several studies tried to use the cosmic void counting number to obt…

Matter Power Spectrum Covariance Matrix from the DEUS-PUR ΛCDM simulations: Mass Resolution and non-Gaussian Errors

Linda Blot, Pier Stefano Corasaniti, Jean-Michel Alimi +2

The upcoming generation of galaxy surveys will probe the distribution of matter in the universe with unprecedented accuracy. Measurements of the matter power spectrum at different…
