The Gravitational Wave Open Science Center (GWOSC), formerly known as the LIGO Open Science Center, is a collaborative initiative dedicated to providing public access to gravitational-wave data products. Established through the combined efforts of the LIGO, Virgo, GEO600, and KAGRA collaborations, GWOSC serves as a central hub for users to access a wide range of data from these observatories via a uniform interface. This approach not only enhances accessibility but also fosters collaboration among scientific teams engaged in cutting-edge research in gravitational wave detection and astrophysics.

GWOSC offers an extensive array of resources, including data downloads, event catalogs, analysis software, educational tutorials, and workshops designed for learners at various levels. By promoting transparency and sharing tools across multiple observatories, GWOSC significantly enhances the scientific community's capacity to analyze gravitational wave phenomena. The center is committed to open science principles, ensuring that all public data releases are available under a Creative Commons license, thus encouraging widespread engagement and research within the gravitational wave community.
