Observational constraints on Diffusion Cosmologies in Unimodular Gravity from DESI DR2
Gabriel Gomez, Guillermo Palma, Norman Cruz
Diffusion functions in unimodular gravity induce a dynamical effective cosmological constant, providing an appealing framework in light of recent DESI observations. In this work, w…
Unimodular Gravity with Arbitrary Diffusion Function: A Dynamical System Reconstruction Approach
Gabriel Gómez, Guillermo Palma, Norman Cruz
We investigate cosmological diffusion models in unimodular gravity within a dynamical systems reconstruction framework. By treating the logarithmic slope of the diffusion sector as…
Viscous Unified Dark Matter Models Under Scrutiny: Uncovering Inconsistencies from Dynamical System Analysis
Guillermo Palma, Gabriel Gomez, Norman Cruz
Viscous unified dark matter models aim to describe the dark sector of the Universe, as the dark matter fluid itself gives rise to an accelerated expansion due to a negative bulk vi…
Scalar Field Dark Matter Around Charged Black Holes
Yuri Ravanal, Gabriel Gómez, Norman Cruz
In this paper, we investigate the behavior of a massive scalar field dark matter scenarios in the large mass limit around a central Reissner-Nordström black hole. This study is mot…
Accretion of Self-interacting Scalar Field Dark Matter Onto a Reissner-Nordström Black Hole
Yuri Ravanal, Gabriel Gómez, Norman Cruz
Self-interacting scalar field dark matter can be seen as an extension of the free case known as Fuzzy dark matter. The interactive case is capable of reproducing the positive featu…
Exploring Models of Running Vacuum Energy with Viscous Dark Matter from a Dynamical System Perspective
Norman Cruz, Gabriel Gomez, Esteban Gonzalez +2
Running vacuum models and viscous dark matter scenarios beyond perfect fluid idealization are two appealing theoretical strategies that have been separately studied as alternatives…
