Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Spacetimes with vector distortion: Inflation from generalised Weyl geometry
Jose Beltrán Jiménez, Tomi S. Koivisto
Spacetime with general linear vector distortion is introduced. Thus, the torsion and the nonmetricity of the affine connection are assumed to be proportional to a vector field (and…
Tensor perturbations in a general class of Palatini theories
Jose Beltrán Jiménez, Lavinia Heisenberg, Gonzalo J. Olmo
We study a general class of gravitational theories formulated in the Palatini approach and derive the equations governing the evolution of tensor perturbations. In the absence of t…
