Varying Gravity from a Modified Fractional Model: Observational Constraints and Slow-Fast Dynamics
Rami Ahmad El-Nabulsi, Genly Leon, Esteban González +1
We investigate a fractional gravity model in which both the Hubble parameter and the gravitational constant evolve dynamically due to fractional renormalization-group effects. The…
Delay Modeling with Conformable and Caputo Derivatives: Analytical and Computational Insights
Yhon Flores, Michel Molina del Sol, Genly Leon +3
This work presents an analytical and computational study of fractional-order delay differential equations formulated using both the conformable and Caputo derivatives. For the conf…
Asymptotic Theorems and Averaging in Scalar Field Cosmology
Genly Leon, Aleksander Kozak, Claudio Michea
We present a hybrid study that combines a concise review of scalar-field cosmology with new analytic developments that integrate averaging reductions for oscillatory regimes with d…
Testing the Coexistence of Dark Energy and Dark Matter with Late-time Observational Data
Shambel Sahlu, Andronikos Paliathanasis, Genly Leon +1
We investigate the viability of a cosmological scenario with interacting dark sector, which can describe the coexistence between dark energy and dark matter. The model possesses an…
Averaging Theory and Dynamical Systems in Cosmology: A Qualitative Study of Oscillatory Scalar-Field Models
Genly Leon, Claudio Michea
We study cosmological models using dynamical systems and averaging methods, encompassing flat and open FLRW geometries as well as the LRS Bianchi types I, III, and V. Under mild re…
- cosmological model with new data samples of cosmological observations
Dorian Araya, Cristian Castillo, Genly Leon +3
We revisit a cosmological model where dark matter (DM) and dark energy (DE) follow barotropic equations of state, allowing deviations from the standard CDM framework (i.e. $w_{d…
Fractional Einstein-Gauss-Bonnet scalar field cosmology
Bayron Micolta-Riascos, Alfredo D. Millano, Genly Leon +3
Our paper introduces a new theoretical framework called the Fractional Einstein--Gauss--Bonnet scalar field cosmology, which has important physical implications. Using fractional c…
Addressing the Hubble tension in Yukawa cosmology?
Kimet Jusufi, Esteban González, Genly Leon
In Yukawa cosmology, a recent discovery revealed a relationship between baryonic matter and the dark sector. The relation is described by the parameter α and the long-range interac…
Charged Black Holes with Yukawa Potential
A. A. Araújo Filho, Kimet Jusufi, B. Cuadros-Melgar +3
This study derives a novel family of charged black hole solutions featuring short- and long-range modifications. These ones are achieved through a Yukawa-like gravitational potenti…
Dark matter signatures of black holes with Yukawa potential
A. A. Araújo Filho, Kimet Jusufi, B. Cuadros-Melgar +1
This study uses a nonsingular Yukawa--modified potential to obtain a static and spherically symmetric black hole solution with a cosmological constant. Such Yukawa--like correction…
