Non-minimal Scalar Effective Cosmology
Callum Hunter, Michael Kenna-Allison
In this work we investigate the most general non-minimally coupled symmetric scalar-tensor effective field theory (EFT) of gravity up to dimension six in the operato…
Vainshtein Mechanism in Generalised Massive Gravity
A. Emir Gumrukcuoglu, Rampei Kimura, Michael Kenna-Allison +1
We present a non-linear analysis of perturbations around cosmological solutions in Generalised Massive gravity. This Lorentz invariant theory is an extension of de Rham, Gabadadze,…
Stable Cosmology in Generalised Massive Gravity
Michael Kenna-Allison, A. Emir Gumrukcuoglu, Kazuya Koyama
We present a thorough analysis of the cosmological perturbations in Generalised Massive Gravity. This is an extension of de Rham-Gabadadze-Tolley theory where the translation invar…
On the viability of bigravity cosmology
Michael Kenna-Allison, A. Emir Gumrukcuoglu, Kazuya Koyama
We revisit the question of viability of bigravity cosmology as a candidate for dark energy. In the context of the low energy limit model, where matter couples to a single metric, w…
