Bouncing cosmology in gravity by order reduction
Bruno J. Barros, Elsa M. Teixeira, Daniele Vernieri
A bouncing universe is a viable candidate to solve the initial singularity problem. Here we consider bouncing solutions in the context of gravity by using an ord…
Anisotropic fluid spheres in Hořava gravity and Einstein-æther theory with a non-static æther
Daniele Vernieri
In this paper we consider spherically symmetric interior spacetimes filled by anisotropic fluids in the context of Hořava gravity and Einstein-aether theory. We assume a specific n…
Covariant action for bouncing cosmologies in modified Gauss-Bonnet gravity
Inês Terrucha, Daniele Vernieri, José P. S. Lemos
Cyclic universes with bouncing solutions are candidates for solving the big bang initial singularity problem. Here we seek bouncing solutions in a modified Gauss-Bonnet gravity the…
Tracker and scaling solutions in DHOST theories
Noemi Frusciante, Ryotaro Kase, Kazuya Koyama +2
In quadratic-order degenerate higher-order scalar-tensor (DHOST) theories compatible with gravitational-wave constraints, we derive the most general Lagrangian allowing for tracker…
