Centre for Gravitational Astrophysics

Organisation profile

Organisation profile

Welcome to the The ANU Centre for Gravitational Astrophysics (CGA). This centre is founded to build a world-leading role for Australia in the science and technology of gravitational wave sources. 

Our research and development is focused on technologies for the improvement of the detection of gravitational waves. The centre strategically unifies the ongoing research at ANU Research School of Physics and ANU Research School of Astronomy and Astrophysics. Active fields of research at CGA span instrumentation, theory, data analysis, source follow-up and multi-messenger astronomy. 

In CGA laboratories, our researchers are working on advanced interferometer configurations and complex control systems, measurement of thermal and quantum noise, optical coating research, Newtonian noise instrumentation, and technologies for space interferometry.

Electromagnetic follow-up of gravitational wave observations are carried out by the SkyMapper telescope and the ANU 2.3m Telescope at the Siding Spring Observatory operated by the ANU Research School of Astronomy and Astrophysics.

The centre incorporates two Australian Research Council Centres of Excellence, Gravitational Wave Discovery (OzGrav) and Engineered Quantum Systems (EQUS), which facilitate integral collaborations with other national and international research teams. 

Analysing data from gravitational wave detectors requires significant computational resources. Centre staff have access to the Australian National Computational Infrastructure on the campus of The Australian National University, the OzSTAR Supercomputing Facility at Swinburne University of Technology provided through OzGrav, and computational facilities of the LIGO Scientific Collaboration.
