2.3m Automation

For gravitational-wave detections and analyses, the raw outputs from the gravitational-wave detectors need to be converted into analysable data through some calibration apparatus. We investigate new techniques to improve calibration accuracy and precision and better integrate the calibration bias into astrophysical analyses.

The next big discovery in gravitational wave astronomy may be a first detection of continuous gravitational waves from rapidly-spinning neutron stars. We aim to develop the data analysis methods needed for such a discovery, and use gravitational wave discoveries and electromagnetic observations of neutron stars to examine fundamental physics.

Digital Interferometry is a new concept for optical interferometry, which combines the high sensitivity of conventional optical interferometry with the robustness of digital modulation/demodulation techniques to achieve a breakthrough combination of sensitivity, ease of use and flexibility.

Fibre Optic Sensor Arrays for Vibrometry and Acoustic Sensing

In 2017, the first discovery of gravitational waves from two colliding neutron stars heralded a new age of multi-messenger astronomy. But what was left over after the collision? We aim to find out.

Ultralight boson particles have been predicted to solve problems in particle and high-energy physics and are compelling dark matter candidates. We develop algorithms and search for these conjectured ultralight bosons around black holes via gravitational-wave observations.

We study the numerical waveforms for the gravitational waves emitted during the black hole ringdown stage, implement tools and data analysis frameworks, and analyze the latest gravitational-wave data to estimate black hole properties and test the general theory of relativity.
