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.…
Cold dark matter protohalo structure around collapse: Lagrangian cosmological perturbation theory versus Vlasov simulations
Shohei Saga, Atsushi Taruya, Stéphane Colombi
We explore the structure around shell-crossing time of cold dark matter protohaloes seeded by two or three crossed sine waves of various relative initial amplitudes, by comparing L…
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…
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…
