On September 1-3 2025 we hosted a workshop on deciHz Gravitational Wave Observations on the Moon and Beyond. We had many interesting discussions on gravitational-wave sources in the deciHz band. We also discussed different experimental approaches to construct sensitive gravitational-wave detectors, including atom interferometry in space, laser interferometers on the Moon or in space, and the idea of using the Moon itself as a giant Weber resonant bar.
