RR Lyrae Stars in Intermediate-age Magellanic Clusters: Membership Probabilities and Delay Time Distribution
Bolivia Cuevas-Otahola, Cecilia Mateu, Ivan Cabrera-Ziri +4
Recent works have challenged our canonical view of RR Lyrae (RRL) stars as tracers of exclusively old populations (~Gyr) by proposing a fraction of these stars to be of…
A stochastic and analytical model of hierarchical fragmentation: The fragmentation of gas structures into young stellar objects in the interstellar medium
Benjamin Thomasson, Isabelle Joncour, Estelle Moraux +4
Molecular clouds are the most important incubators of young stars clustered in various stellar structures whose spatial extension can vary from a few AU to several thousand AU. Alt…
Development of large-volume TeO bolometers for the CROSS decay search experiment
F. T. Avignone, A. S. Barabash, V. Berest +36
We report on the development of thermal detectors based on large-size tellurium dioxide crystals (45x45x45 mm), containing tellurium enriched in Te to about 91%, for the CR…
Exploring the Evolution of Nonlinear Electrodynamics in the Universe: A Dynamical Systems Approach
Ricardo García-Salcedo, Isidro Gómez-Vargas, Tame González +2
This paper investigates the dynamics of cosmological models incorporating nonlinear electrodynamics (NLED), focusing on their stability and causality. We explore two specific NLED…
Cloud structure and young star distribution in the Dragonfish complex
Nestor Sanchez, Elisa Nespoli, Marta Gonzalez +1
One way to shed some light on the star formation process this process is to analyse the relationship between the spatial distributions of gas and newly formed stars. In order to ob…
Kinetic Parameters analysis of GdAlO based on thermoluminescent phenomenon

Cosmological parameter estimation with Genetic Algorithms
Ricardo Medel-Esquivel, Isidro Gómez-Vargas, Alejandro A. Morales Sánchez +2
Genetic algorithms are a powerful tool in optimization for single and multi-modal functions. This paper provides an overview of their fundamentals with some analytical examples. In…
Recovering discrete delayed fractional equations from trajectories
J. Alberto Conejero, Òscar Garibo-i-Orts, Carlos Lizama
We show how machine learning methods can unveil the fractional and delayed nature of discrete dynamical systems. In particular, we study the case of the fractional delayed logistic…
