Nonlocal Gravity, Restricted CPL Dynamics and DESI Constraints
Luca Amendola, Ismael Ayuso, Amlan Chakraborty +2
Nonlocal modifications of gravity provide a theoretically motivated framework in which cosmic acceleration can emerge dynamically without introducing a fundamental cosmological con…
Forecasting Coupled Dark Energy Parameters with the One-Loop Galaxy Power Spectrum
Bilal Tüdes, Luca Amendola
We forecast constraints on the parameters of the coupled dark energy model using DESI and Euclid data with the one-loop galaxy power spectrum. We investigate the distinguishability…
Constraints on Coupled Dark Energy in the DESI Era
Adrià Gómez-Valent, Ziyang Zheng, Luca Amendola
We investigate the current viability of a well-known coupled dark energy scenario in which cold dark matter (DM) interacts with a spin-0 dark energy component through a non-trivial…
One-loop kernels in scale-dependent Horndeski theory
Ziyang Zheng, Hanqiong Jia, Bilal Tüdes +3
We investigate the nonlinear evolution of cosmological perturbations in theories with scale-dependent perturbation growth, first in general and then focusing on Horndeski gravity.…
Nonlinear dynamics in Horndeski gravity: a renormalized approach to effective gravitational coupling
Luca Amendola, Carla Bernal, Radouane Gannouji
This paper develops a renormalized perturbation theory framework for nonlinear structure formation in a broad class of modified gravity models that exhibit Vainshtein screening, wi…
Non-linear Cosmological Perturbations for Coupled Dark Energy
Bilal Tüdes, Luca Amendola
We derive the one-loop perturbation kernels for a minimal modified gravity model in which dark energy is coupled to dark matter via a constant coupling. We derive the time-dependen…
