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…
Cosmological test of local position invariance from the asymmetric galaxy clustering
Shohei Saga, Atsushi Taruya, Michel-Andrès Breton +1
The local position invariance (LPI) is one of the three major pillars of Einstein equivalence principle, ensuring the space-time independence on the outcomes of local experiments.…
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…
Impact of lensing magnification on the analysis of galaxy clustering in redshift space
Michel-Andrès Breton, Sylvain de la Torre, Jade Piat
We study the impact of lensing magnification on the observed three-dimensional galaxy clustering in redshift space. We used the RayGal suite of N-body simulations, from which we ex…
Detectability of the gravitational redshift effect from the asymmetric galaxy clustering
Shohei Saga, Atsushi Taruya, Michel-Andrès Breton +1
It has been recently recognized that the observational relativistic effects, mainly arising from the light propagation in an inhomogeneous universe, induce the dipole asymmetry in…
