Euclid: Forecast constraints on consistency tests of the CDM model
S. Nesseris, D. Sapone, M. Martinelli +112
The standard cosmological model is based on the fundamental assumptions of a spatially homogeneous and isotropic universe on large scales. An observational detection of a violation…
Late-transition vs smooth deformation models for the resolution of the Hubble crisis
George Alestas, David Camarena, Eleonora Di Valentino +4
Gravitational transitions at low redshifts () have been recently proposed as a solution to the Hubble and growth tensions. Such transitions would naturally lead to a trans…
The Copernican principle in light of the latest cosmological data
David Camarena, Valerio Marra, Ziad Sakr +1
We pursue a program to confront observations with inhomogeneous extensions of the FLRW metric. The main idea is to test the Copernican principle rather than assuming it a priori. W…
On the use of the local prior on the absolute magnitude of Type Ia supernovae in cosmological inference
David Camarena, Valerio Marra
A dark-energy which behaves as the cosmological constant until a sudden phantom transition at very-low redshift () seems to solve the >4 disagreement between the local an…
