Arrows of time in bouncing cosmologies

Marco de Cesare

Different approaches to quantum gravity, such as loop quantum cosmology and group field theory, predict the resolution of the initial cosmological singularity via a bounce: a regul…

Perturbations of bimetric gravity on most general spherically symmetric spacetimes

David Brizuela, Marco de Cesare, Araceli Soler Oficial

We present a formalism to study linear perturbations of bimetric gravity on any spherically symmetric background, including dynamical spacetimes. The setup is based on the Gerlach-…
