A thermodynamic point of view on dark energy models

Vincenzo F. Cardone, Ninfa Radicella, Antonio Troisi

We present a conjugate analysis of two different dark energy models investigating both their agreement with recent data and their thermodynamical properties. The successful match w…

The maximum sizes of large scale structures in alternative theories of gravity

Sourav Bhattacharya, Konstantinos F. Dialektopoulos, Antonio Enea Romano +2

The maximum size of a cosmic structure is given by the maximum turnaround radius -- the scale where the attraction due to its mass is balanced by the repulsion due to dark energy.…

Cosmology with gamma-ray bursts: I. The Hubble diagram through the calibrated - correlation

Marek Demianski, Ester Piedipalumbo, Disha Sawant +1

Gamma-ray bursts are the most energetic explosions in the Universe. They are detectable up to very high redshifts, therefore can be used to study the expansion rate of the Universe…

Cosmology with gamma-ray bursts: II Cosmography challenges and cosmological scenarios for the accelerated Universe

Marek Demianski, Ester Piedipalumbo, Disha Sawant +1

Context. Explaining the accelerated expansion of the Universe is one of the fundamental challenges in physics today. Cosmography provides information about the evolution of the uni…

No need for dark matter in galaxy clusters within Galileon theory

Vincenzo Salzano, David F. Mota, Mariusz P. Dabrowski +1

Modified gravity theories with a screening mechanism have acquired much interest recently in the quest for a viable alternative to General Relativity on cosmological scales, given…
