Bayesian Inference of Primordial Magnetic Field Parameters from CMB with Spherical Graph Neural Networks
Juan Alejandro Pinto Castro, Héctor J. Hortúa, Jorge Enrique García-Farieta +1
Deep learning has emerged as a transformative methodology in modern cosmology, providing powerful tools to extract meaningful physical information from complex astronomical dataset…
Spherically Symmetric Potentials in Quadratic Gravity
Roger Anderson Hurtado
We study the gravitational potential generated by static, spherically symmetric matter distributions in a quadratic gravity model. In the weak-field regime, the linearized f…
Linearized Gravity in the Starobinsky Model: Perturbative Deviations from General Relativity
Roger Anderson Hurtado
In this work, we linearize the field equations of gravity using the Starobinsky model, , and examine the modifications to General Relativity. We derive an equa…
Hypergeometric viable models in gravity
Roger Hurtado, Robel Arenas
A cosmologically viable hypergeometric model in the modified gravity theory is found from the need for asintoticity towards CDM, the existence of an inflection point in t…
Spherically symmetric and static solutions in gravity coupled with EM fields
Roger A. Hurtado, Jose R. Arenas
Solutions of field equations in gravity are found for a spherically symmetric and static spacetime in the Born-Infeld (BI) non-linear electrodynamics. It is found that the m…
Scalar-field potential for viable models in theory
Roger A. Hurtado, Robel Arenas
The theory of gravity can be expressed as a scalar tensor theory with a scalar degree of freedom . By a conformal transformation, the action and its Gibbons-York-Hawking…
Gravitational Lensing by Spherical Lenses
Roger Hurtado, Leonardo Castaneda, Juan M. Tejeiro
In this work we introduced a new proposal to study the gravitational lensing theory by spherical lenses, starting from its surface mass density written in terms of a decreas…
