Testing Non-minimally Coupled BEC Dark Matter with Gravitational Waves
Dimitar Ivanov, Stefano Liberati
We study the phenomenology associated to non-minimally coupled dark matter. In particular, we consider the model where the non-minimal coupling arises from the formation of relativ…

Perturbative treatment of the luminosity distance
Dimitar Ivanov, Stefano Liberati, Matteo Viel +1
We derive a generalized luminosity distance versus redshift relation for a linearly perturbed FLRW (Friedmann-Lemaitre-Robertson-Walker) metric with two scalar mode excitations. We…

Non-perturbative results for the luminosity and area distances
Dimitar Ivanov, Stefano Liberati, Matteo Viel +1
The notion of luminosity distance is most often defined in purely FLRW (Friedmann-Lemaitre-Robertson-Walker) cosmological spacetimes, or small perturbations thereof. However, the a…
