Spherical collapse in Galileon gravity: fifth force solutions, halo mass function and halo bias
Alexandre Barreira, Baojiu Li, Carlton Baugh +1
We study spherical collapse in the Quartic and Quintic Covariant Galileon gravity models within the framework of the excursion set formalism. We derive the nonlinear spherically sy…
Simulating the quartic Galileon gravity model on adaptively refined meshes
Baojiu Li, Alexandre Barreira, Carlton M. Baugh +4
We develop a numerical algorithm to solve the high-order nonlinear derivative-coupling equation associated with the quartic Galileon model, and implement it in a modified version o…
Nonlinear structure formation in the Cubic Galileon gravity model
Alexandre Barreira, Baojiu Li, Wojciech A. Hellwing +2
We model the linear and nonlinear growth of large scale structure in the Cubic Galileon gravity model, by running a suite of N-body cosmological simulations using the {\tt ECOSMOG}…
The parameter space in Galileon gravity models
Alexandre Barreira, Baojiu Li, Ariel Sanchez +2
We present the first constraints on the full parameter space of the Galileon modified gravity model, considering both the cosmological parameters and the coefficients which specify…
