Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

We review recent progress in massive gravity. We start by showing how different theories of
massive gravity emerge from a higher-dimensional theory of general relativity, leading to the …

This review is dedicated to recent progress in the field of classical, interacting, massive spin-
2 theories, with a focus on ghost-free bimetric theory. We will outline its history and its …

A bstract In massive gravity and in bimetric theories of gravity, two constraints are needed to
eliminate the two phase-space degrees of freedom of the Boulware-Deser ghost. For …

We obtain the general cosmological evolution equations for a classically consistent theory of
bimetric gravity. Their analytic solutions are demonstrated to generically allow for a cosmic …

We study cosmological perturbations of self-accelerating universe solutions in the recently
proposed nonlinear theory of massive gravity, with general matter content. While the broken …

A bstract We study the background cosmology of the ghost-free, bimetric theory of gravity.
We perform an extensive statistical analysis of the model using both frequentist and …

We present an exact spherical black hole solution in de Rham, Gabadadze, and Tolley
(dRGT) massive gravity for a generic choice of the parameters in the theory, and also …

A bstract We study cosmological perturbations for a ghost free massive gravity theory
formulated with a dynamical extra metric that is needed to massive deform GR. In this …
