Our research covers all aspects of gravitational wave science: from detector technology to search algorithms; from numerical modelling to data analysis; and, from astrophysical inference to fundamental physics.

About

We're one of the leading groups in the world studying all aspects of gravitational-wave physics. As part of the international LIGO-Virgo-KAGRA collaboration we play a key part in global efforts to promote and conduct gravitational-wave detection and science.

Our aim is to explore the full potential of astrophysical gravitational waves. This includes improving the sensitivity of detectors, performing deep searches of the data, improving the computer algorithms used for such searches, and interpreting the search results. All of this contributes to a deeper understanding of black holes, neutron stars, and other sources of the gravitational waves we detect.

We work on detector development, searches for signals from inspiralling compact objects such as black holes and neutron stars, and on searches for burst-like signals that may be expected from supernovae or yet unknown sources. We model expected signals from coalescing black holes with ever-greater precision and estimate astrophysical parameters of identified signals in the data stream from the LIGO-Virgo-KAGRA detector network.

A number of our Institute’s members perform key leadership roles in the international collaboration. Using similar detector technology, we search for hints about fundamental physics such as quantum gravity.

Finally, we study what the findings tell us about astrophysics and what we can learn about the Universe, working with colleagues across research groups.

Projects

Gravitational-wave detector development

We are dedicated to developing new technologies to improve both the sensitivity and operational time of gravitational-wave detectors.

Astrophysical modelling of gravitational-wave sources

Using high-performance computing simulations and analytic theory, we explore the formation and evolution of compact binaries.

Electromagnetic counterparts of gravitational-wave signals

Our research focuses on identifying and characterising the electromagnetic signals emitted by gravitational-wave sources.

Observational Gravitational-wave Astrophysics

Within the international LIGO-Virgo-KAGRA collaboration we are continuously analyzing the data from those Gravitational-wave observatories.

Quantum-enhanced interferometry for fundamental physics - lab work

Quantum-enhanced interferometry for fundamental physics

The measurements done in this experiment will allow for either a detection of a signature of quantum gravity, or they will set an upper limit on the strength of correlated quantum fluctuations.
