A Fast Route to Modified Gravitational Growth
Tessa Baker, Pedro G. Ferreira, Constantinos Skordis
The growth rate of the large-scale structure of the universe has been advocated as the observable par excellence for testing gravity on cosmological scales. By considering linear-o…
Models of coupled dark matter to dark energy
A. Pourtsidou, C. Skordis, E. J. Copeland
We present three distinct types of models of dark energy in the form of a scalar field which is explicitly coupled to dark matter. Our construction draws from the pull-back formali…
The Dark Energy Cosmic Clock: A New Way to Parametrise the Equation of State
Ewan R. M. Tarrant, Edmund J. Copeland, Antonio Padilla +1
We propose a completely new parametrisation of the dark energy equation of state, which uses the dark energy density, as a cosmic clock. We expand the equation of state in a…
Cosmological constraints on Brans-Dicke theory
A. Avilez, C. Skordis
We report strong cosmological constraints on the Brans-Dicke (BD) theory of gravity using Cosmic Microwave Background data from Planck.We consider two types of models. First, the i…
