Important change due to COVID-19: the workshop will take place online, read below!

The Black Hole Perturbation Toolkit (BHPToolkit) is a global collaboration dedicated to creating an open-source repository of software, data and results related to black hole perturbation theory. These tools are important in the theory of gravitational waves, specifically in the modelling of inspirals of stellar-mass objects into massive black holes. The BHPToolkit workshops bring together researchers that are already using and developing the toolkit as well as scientists and students that are looking to do so.

Due to the Covid-19 situation, the hosting country of the Spring 2020 BHPToolkit workshop, Czechia, has restricted access to foreigners and banned public events. Even though there is talk about loosening these restrictions in the near future, we cannot guarantee that you would be able to come and/or that we would be able to hold the workshop by May. Consequently, we were forced to cancel the Prague workshop.

Instead of the face-to-face meeting, we will hold a virtual workshop consisting of a chain of video-conferences and a hackathon that will take place on the same dates ( May 25-27, GMT daytimes ). We will post the necessary organizational details a few weeks before the date of the virtual workshop. Additionally, we plan to use the already approved COST funding to organize a face-to-face workshop in early Spring 2021.

If you need a confirmation that you planned to attend the event and it got cancelled, or if you have any other questions, please write an email to vojtech.witzany at You can still register for the workshop on the Registration page to receive e-mail alerts.
