A modern halo streaming model for redshift space distortions
Cheng-Zong Ruan, Baojiu Li, Carlton M. Baugh +3
Accurate modelling of redshift-space distortions (RSD) in galaxy clustering is essential for extracting cosmological information from current and forthcoming large-scale structure…
Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
Non-linear structure formation with elastic interactions in the dark sector
Jose Beltrán Jiménez, David Figueruelo, David F. Mota +1
Cosmological models where dark matter interacts with dark energy via a pure momentum transfer and with no energy exchange (i.e. elastic) provide compelling scenarios for addressing…
Lorentz Violation with Gravitational Waves: Constraints from NANOGrav and IPTA Data
Alireza Allahyari, Mohammadreza Davari, David F. Mota
We explore a theoretical framework in which Lorentz symmetry is explicitly broken by incorporating derivative terms of the extrinsic curvature into the gravitational action. These…
Euclid preparation LXIII. Simulations and nonlinearities beyond CDM. 2. Results from non-standard simulations
Euclid Collaboration, G. Rácz, M. -A. Breton +275
The Euclid mission will measure cosmological parameters with unprecedented precision. To distinguish between cosmological models, it is essential to generate realistic mock observa…
Euclid preparation. Simulations and nonlinearities beyond CDM. 1. Numerical methods and validation
Euclid Collaboration, J. Adamek, B. Fiorini +268
To constrain models beyond CDM, the development of the Euclid analysis pipeline requires simulations that capture the nonlinear phenomenology of such models. We present an over…
