Signs of Interacting Vacuum and Dark Matter in the Universe

Joan Sola, A. Gomez-Valent, J. de Cruz Perez

We consider the impact of dynamical dark energy (DDE) in the possible solution of the existing tensions in the CDM. We test both interacting and non-interacting DE models with d…

Consistency of local and astrophysical tests of the stability of fundamental constants

C. J. A. P. Martins, M. Vila Miñana

Tests of the stability of nature's fundamental constants are one of the cornerstones of the ongoing search for the new physics which is required to explain the recent acceleration…

The local and distant Universe: stellar ages and

Raul Jimenez, Andrea Cimatti, Licia Verde +2

The ages of the oldest stellar objects in our galaxy provide an independent test of the current cosmological model as they give a lower limit to the age of the Universe. Recent acc…

Measuring the Homogeneity of the Universe Using Polarization Drift

Raul Jimenez, Roy Maartens, Ali Rida Khalifeh +3

We propose a method to probe the homogeneity of a general universe, without assuming symmetry. We show that isotropy can be tested at remote locations on the past lightcone by comp…

How to relax the cosmological neutrino mass bound

Isabel M. Oldengott, Gabriela Barenboim, Sarah Kahlen +2

We study the impact of non-standard momentum distributions of cosmic neutrinos on the anisotropy spectrum of the cosmic microwave background and the matter power spectrum of the la…
