On the growth of structure in theories with a dynamical preferred frame
T. G Zlosnik, P. G. Ferreira, G. D. Starkman
We study the cosmological stability of a class of theories with a dynamical preferred frame. For a range of actions, we find cosmological solutions which are compatible with observ…
Generalized Einstein-Aether theories and the Solar System
Camille Bonvin, Ruth Durrer, Pedro G. Ferreira +2
It has been shown that generalized Einstein-Aether theories may lead to significant modifications to the non-relativistic limit of the Einstein equations. In this paper we study th…
The Cosmology of a Universe with Spontaneously-Broken Lorentz Symmetry
P. G. Ferreira, B. M. Gripaios, R. Saffari +1
A self consistent effective field theory of modified gravity has recently been proposed with spontaneous breaking of local Lorentz invariance. The symmetry is broken by a vector fi…
Modifying gravity with the Aether: an alternative to Dark Matter
T. G Zlosnik, P. G Ferreira, G. D Starkman
There is evidence that Newton and Einstein's theories of gravity cannot explain the dynamics of a universe made up solely of baryons and radiation. To be able to understand the pro…
