Early Modified Gravity: Implications for Cosmology
Philippe Brax, Carsten van de Bruck, Sebastien Clesse +2
We study the effects of modifications of gravity after Big Bang Nucleosynthesis (BBN) which would manifest themselves mainly before recombination. We consider their effects on the…
Novel Probes of Gravity and Dark Energy
Bhuvnesh Jain, Austin Joyce, Rodger Thompson +29
The discovery of cosmic acceleration has stimulated theorists to consider dark energy or modifications to Einstein's General Relativity as possible explanations. The last decade ha…
Cosmological Tests of the Disformal Coupling to Radiation
Philippe Brax, Clare Burrage, Anne-Christine Davis +1
Light scalar fields can naturally couple disformally to Standard Model fields without giving rise to the unacceptably large fifth forces usually associated with light scalars. We s…
Systematic simulations of modified gravity: chameleon models
Philippe Brax, Anne-C. Davis, Baojiu Li +2
In this work we systematically study the linear and nonlinear structure formation in chameleon theories of modified gravity, using a generic parameterisation which describes a larg…
Dynamics of Supersymmetric Chameleons
Philippe Brax, Anne-Christine Davis, Jeremy Sakstein
We investigate the cosmological dynamics of a class of supersymmetric chameleon models coupled to cold dark matter fermions. Supergravity corrections ensure that these models are e…
