Cosmology and Gravitation - UAZ

This repository is a compilation of various numerical tools developed by the Cosmology and Gravitation group at the Unidad Académica de Física affiliated with the Autonomous University of Zacatecas.

The numerical codes available in the repository were created with the support of the project Null Geodesics Around Black Holes in Modified Gravity and were developed within the framework of the publications detailed below.

About the group

Our research focuses on exploring and identifying potential signatures of alternative models to General Relativity, both at the cosmological scale and within compact objects. Additionally, within the framework of General Relativity, we investigate possible signatures from compact objects composed of non-baryonic matter.

Check out our home page for more information. (Under construction)
