PySCo-EFT and ECOSMOG-EFT: a tandem of N-body simulation codes for the Effective Field Theory of Dark Energy

Himanish Ganjoo, Yann Rasera, Emilio Bellini +18

Modified gravity theories constitute viable alternatives to the standard cosmological model for explaining the observed late-time accelerated expansion of the Universe. The Effecti…

The RayGalGroupSims cosmological simulation suite for the study of relativistic effects: an application to lensing-matter clustering statistics

Y. Rasera, M-A. Breton, P-S. Corasaniti +8

General Relativistic effects on the clustering of matter in the universe provide a sensitive probe of cosmology and gravity theories that can be tested with the upcoming generation…

Magrathea-Pathfinder: A 3D adaptive-mesh code for geodesic ray tracing in -body simulations

Michel-Andrès Breton, Vincent Reverdy

We introduce Magrathea-Pathfinder, a relativistic ray-tracing framework that can reconstruct the past light cone of observers in cosmological simulations. The code directly compute…

Exploration and Exploitation in Symbolic Regression using Quality-Diversity and Evolutionary Strategies Algorithms

J. -P. Bruneton, L. Cazenille, A. Douin +1

By combining Genetic Programming, MAP-Elites and Covariance Matrix Adaptation Evolution Strategy, we demonstrate very high success rates in Symbolic Regression problems. MAP-Elites…

Elliptic solutions of generalized Brans-Dicke gravity with a non-universal coupling

J. -M. Alimi, A. A. Golubtsova, V. Reverdy

We study a model of the generalized Brans-Dicke gravity presented in both the Jordan and in the Einstein frames, which are conformally related. We show that the scalar field equati…

Cosmic variance limited Baryon Acoustic Oscillations from the DEUS-FUR CDM simulation

Yann Rasera, Pier-Stefano Corasaniti, Jean-Michel Alimi +3

We investigate the non-linear evolution of Baryon Acoustic Oscillations (BAO) in the low-redshift matter power spectrum from the DEUS-FUR CDM model simulation. This is the first…

DEUS Full Observable ΛCDM Universe Simulation: the numerical challenge

Jean-Michel Alimi, Vincent Bouillot, Yann Rasera +6

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…
