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…
Strong-lensing degeneracies of black holes embedded in self-interacting scalar field dark matter halos
Mohsen Fathi, Gabriel Gómez
In this paper, we explore the strong gravitational lensing properties of black holes embedded in self-interacting scalar field dark matter halos, together with NFW-type configurati…
Perturbative Effects of Dark Matter Environments on Black Hole Shadows
Gabriel Gomez
Constructing spacetime solutions that describe black holes embedded in dark matter environments is a crucial step toward probing the properties of dark matter in the strong-field r…
