Swiss-cheese cosmologies with variable and from the renormalization group

Fotios K. Anagnostopoulos, Alfio Bonanno, Ayan Mitra +1

A convincing explanation for the nature of the dark energy and dark matter is still missing. In recent works a RG-improved swiss-cheese cosmology with an evolving cosmological cons…

First evidence that non-metricity f(Q) gravity could challenge CDM

Fotios K. Anagnostopoulos, Spyros Basilakos, Emmanuel N. Saridakis

We propose a novel model in the framework of gravity, which is a gravitational modification class arising from the incorporation of non-metricity. The model has General Rela…

IR quantum gravity solves naturally cosmic acceleration and its coincidence problem

Fotios K. Anagnostopoulos, Georgios Kofinas, Vasilios Zarikas

The novel idea is that the undergoing accelerated expansion of the universe happens due to infrared quantum gravity modifications at intermediate astrophysical scales of galaxies o…

Observational constraints on Myrzakulov gravity

Fotios K. Anagnostopoulos, Spyros Basilakos, Emmanuel N. Saridakis

We use data from Supernovae (SNIa) Pantheon sample, from Baryonic Acoustic Oscillations (BAO), and from cosmic chronometers measurements of the Hubble parameter (CC), alongside arg…

Observational constraints on Barrow holographic dark energy

Fotios K. Anagnostopoulos, Spyros Basilakos, Emmanuel N. Saridakis

We use observational data from Supernovae (SNIa) Pantheon sample, as well as from direct measurements of the Hubble parameter from the cosmic chronometers (CC) sample, in order to…

Bayesian analysis of gravity using data

Fotios K. Anagnostopoulos, Spyros Basilakos, Emmanuel N. Saridakis

We use observational data from Supernovae (SNIa) Pantheon sample, from direct Hubble constant measurements with cosmic chronometers (CC), from the Cosmic Microwave Background shift…
