Fully relativistic predictions in Horndeski gravity from standard Newtonian N-body simulations
Guilherme Brando, Kazuya Koyama, David Wands +3
The N-body gauge allows the introduction of relativistic effects in Newtonian cosmological simulations. Here we extend this framework to general Horndeski gravity theories, and inv…
Relativistic Corrections to the Growth of Structure in Modified Gravity
Guilherme Brando, Kazuya Koyama, David Wands
We present a method to introduce relativistic corrections including linear dark energy perturbations in Horndeski theory into Newtonian simulations based on the N-body gauge approa…
Exploring Early and Late Cosmology with Next Generation Surveys
Guilherme Brando, Eric V. Linder
Perturbations from inflation evolve into large scale structure of the late universe, and encode abundant cosmic structure formation physics. We allow freedom in the primordial powe…
Modified Gravity Away from a CDM Background
Guilherme Brando, Felipe T. Falciano, Eric V. Linder +1
Within the effective field theory approach to cosmic acceleration, the background expansion can be specified separately from the gravitational modifications. We explore the impact…
A quasi-matter bounce equivalent to Starobinsky inflation
L. F. Guimarães, F. T. Falciano, G. Brando
In this paper we construct a bounce model that mimics the Starobinsky inflationary model. Our construction relies on Wands' duality, which shows that the Mukhanov-Sasaki equation h…
Stiff Matter Solution in Brans-Dicke Theory and The General Relativity Limit
G. Brando, J. C. Fabris, F. T. Falciano +1
Generally the Brans-Dicke theory reduces to General Relativity in the limit if the scalar field goes as . However, it is also known that there are…
