Non-parametric reconstruction of cosmological observables using Gaussian Processes Regression
José de Jesús Velázquez, Luis A. Escamilla, Purba Mukherjee +1
The current accelerated expansion of the Universe remains ones of the most intriguing topics in modern cosmology, driving the search for innovative statistical techniques. Recent a…
Do we need wavelets in the late Universe?
Luis A. Escamilla, Emre Özülker, Özgür Akarsu +2
We parameterize the Hubble function by adding Hermitian wavelets to the Hubble radius of CDM. This allows us to build Hubble functions that oscillate around CDM at late times…
Exploring the Hubble tension with a late time Modified Gravity scenario
Luis A. Escamilla, Donatella Fiorucci, Giovanni Montani +1
We investigate a modified cosmological model aimed at addressing the Hubble tension, considering revised dynamics in the late Universe. The model introduces a parameter affecti…
Multidimensionality of the Hubble tension: the roles of and
Davide Pedrotti, Jun-Qian Jiang, Luis A. Escamilla +2
The Hubble tension is inherently multidimensional, and bears important implications for parameters beyond . We discuss the key role of the matter density parameter and t…
Kinetic Model for Dark Energy - Dark Matter Interaction: Scenario for the Hubble Tension
Giovanni Montani, Nakia Carlevaro, Luis A. Escamilla +1
We analyze a model for Dark Energy - Dark Matter interaction, based on a decaying process of the former into the latter. The dynamical equations are constructed following a kinetic…
Testing an oscillatory behavior of dark energy
Luis A. Escamilla, Supriya Pan, Eleonora Di Valentino +3
The main aim of this work is to use a model-independent approach, along with late-time observational probes, to reconstruct the dark energy (DE) equation of state .…
