Tools to constrain PBHs and the GeV excess using continuous gravitational waves

cw_constrain

---

Overview

cw_constrain is a Python package designed to provide tools and methods for constraining PBH abundance and the MSP hypothesis for the GeV excess using upper limits derived from continuous gravitational wave searches on real LIGO-Virgo-KAGRA data. It includes modules for analyzing GeV excess constraints, primordial black hole constraints, and shared utilities.

Features

• Calculate constraints on MSP luminosity functions that explain the GeV excess using your own luminosity function, your own rotational frequency distribution and/or your own ellipticity distribution.
• Compute constraints on the fraction of dark matter that primordial black hole (PBHs) could compose using your own mass function or PBH formation model.
• Utility functions shared across modules for data processing
• Well-structured package suitable for scientific research and data analysis
