A Strong Cosmologically Coupled Mass Growth Solution in Linearized General Relativity
Kevin S. Croker, Joshua Cohon, Viktor T. Toth +13
DESI Data Release 2 has heightened interest in cosmologically coupled black holes (CCBHs) as an explanation for accelerating late-time expansion, but known models for CCBHs grow to…
Testing modified gravity theories with marked statistics
Alejandro Aviles
In the last two decades, Modified Gravity (MG) models have been proposed to explain the accelerated expansion of the Universe. However, one of the main difficulties these theories…
Emerging the dark sector from thermodynamics of cosmological systems with constant pressure
Alejandro Aviles, Norman Cruz, Jaime Klapp +1
We investigate the thermodynamics of general fluids that have the constriction that their pressure is constant. For example, this happens in the case of pure dust matter, for which…
Precision cosmology with Padé rational approximations: theoretical predictions versus observational limits
Alejandro Aviles, Alessandro Bravetti, Salvatore Capozziello +1
We propose a novel approach for parameterizing the luminosity distance, based on the use of rational "Padé" approximations. This new technique extends standard Taylor treatments, o…
Cosmographic reconstruction of cosmology
Alejandro Aviles, Alessandro Bravetti, Salvatore Capozziello +1
A cosmographic reconstruction of models is here revised in a model independent way by fixing observational bounds on the most relevant terms of the …
Updated constraints on gravity from cosmography
Alejandro Aviles, Alessandro Bravetti, Salvatore Capozziello +1
We address the issue of constraining the class of able to reproduce the observed cosmological acceleration, by using the so called cosmography of the universe. We…
