The goals of this project are to develop breakthrough technologies that will enable third generation ground-based GW detectors, create a conceptual design for a kilohertz GW detector, and lay the technological foundations for Australia to participate in a space-based GW detection such as LISA. These remarkable future detectors operate in complementary frequency bands ranging from 10 mHz to 5 kHz, will answer key questions about the workings of the Universe: from how galaxies form and evolve to how matter behaves at extreme densities and temperatures.

​OzGrav is positioned to contribute enabling technologies to these future detectors so that Australia benefits from the ground-breaking science they will enable. The detectors are also compelling in their own right as they push the limits of optical measurement technology and probe fundamental science. Future detectors may make it possible to place a human-size optomechanical system into its quantum ground state, potentially allowing investigation of how gravitational fields affect quantum systems.
