Again! Second set of merging black holes found

A second binary black hole merger has been found by LIGO, cementing the new field of gravitational wave astronomy. The paper describing the discovery is published in Physical Review Letters and a science summary can be found on the LIGO website.

The Centre for Gravitational Physics (CGP) was founded to undertake research and development for instrumentation for the detection of gravitational waves. These technologies use laser interferometers to sense tiny displacements. At the CGP we developed and installed instrumentation and control systems in the Laser Interferometer Gravitational wave Observatory (LIGO) and in the GRACE Follow-On mission. We have also spun-off gravitational wave detection technologies into a number of related research fields.

Most of the research in the group is directed towards gravitational wave detection, the related area of high precision measurement, and the exploitation of gravitational waves for astronomy. Our specific research interests include advanced interferometer configurations and control systems, measurement of thermal and quantum noise, quantum noise cancellation and quantum-non-demolition techniques, data analysis, digital interferometry, Gravity Recovery and Climate Experiment (GRACE) Follow-On Mission, and frequency stabilisation for the Laser Interferometer Space Antenna (eLISA). For further information on our research please have a look at the various research pages. The group has a purpose built laboratory for experimental work and access to premier computing facilities. The group also has links with the ANU Quantum Optics Group.

The ANU Centre for Gravitational Physics is located within the Department of Quantum Science. We are a member institution of the Australian Consortium for Interferometric Gravitational wave Astronomy (ACIGA). We work closely with the Laser Interferometer Gravitational-wave Observatory (LIGO) and are members of the LIGO Scientific Collaboration (LSC) and have taken on specific responsibilities in the design and construction of Advanced LIGO (AdvLIGO).
