The actual knowledge of the structure and future evolution of our universe is based on the use of cosmological models, which can be tested through the so-called ’probes’, namely astrophysical phenomena, objects or structures with peculiar properties that can help to discriminate among different cosmological models. Among all the existing probes, of particular importance are the Supernovae Ia (SNe Ia) and the Gamma Ray Bursts (GRBs): the former are considered among the best standard candles so…

The difference from 4 to 6 σ in the Hubble constant (H0) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by…
$H_0$ as a Universal FLRW Diagnostic
- Physics

We reverse the logic behind the apparent existence of H0-tension, to design diagnostics for cosmological models. The basic idea is that the non-constancy of H0 inferred from observations at different…
Cosmological perturbation theory in f(Q,T) gravity

Although general relativity (GR) has been precisely tested at the solar system scale, precise tests at a galactic or cosmological scale are still relatively insufficient. Here, in order to test GR at…

A Cosmological Underdensity Does Not Solve the Hubble Tension

A potential solution to the Hubble tension is the hypothesis that the Milky Way is located near the center of a matter underdensity. We model this scenario through the Lemâıtre–Tolman–Bondi formalism…
