The Black Hole Perturbation Toolkit is a centralized collection of software and data resources designed to support research in black hole perturbation theory. It enables the modeling of gravitational waves emitted by small mass-ratio binaries and by black hole ringdowns—both of which are important sources for the future space-based gravitational wave observatory, LISA.
The project’s broader aim is to reduce the time researchers spend developing computational tools, allowing them to focus more on physics. Over the years, many black hole perturbation codes have been developed independently by different researchers and groups. The Toolkit consolidates key components of these efforts into a unified, accessible resource for the wider community.
The BHPToolkit is composed of a range of modular tools that users can install individually based on their specific research needs. The Toolkit and Data Repository provides an overview of all available tools and datasets, each with dedicated pages offering installation instructions and documentation.
