The PBHBeta library is a computational tool designed to calculate constraints on the abundance of Primordial Black Holes (PBHs) and the power spectrum (PS) in cosmological scenarios featuring a non-standard evolution phase between the end of inflation and Big Bang Nucleosynthesis (BBN).

Warning

This project is under development.

Note

This code has been tested exclusively with Python version 3.9, and we strongly recommend using it with versions higher than this (Python 3.x and above).

The GitHub repository and PyPI package for PBHBeta include the essential libraries necessary to run PBHBeta. However, these dependencies must be imported into the notebook or console for the functions to become accesible. Refer to the requeriments and installation sections.
