This is an exciting time in gravitational-wave astronomy! LIGO, Virgo, and KAGRA are currently in their fourth observing run (O4). Data from the past three observing runs (O1, O2, and O3) are publicly available, and include over 90 detections of compact object mergers.

This Open Data Workshop is the 7th in a series of workshops that began in 2018. Participants will receive a crash-course in gravitational-wave data analysis. The workshop includes lectures by data analysis experts, hands on experience with software tutorials, and a data challenge designed to test your new skill in GW data analysis.

This year's workshop will still be hosted in a hybrid style at the national museum of the natural science in Taiwan following the 11th KAGRA International Workshop. Participants can join in-person in Taiwan or you are welcome to join the closest study hub or participate online.
