Unlocking the secrets of the universe
From frontier tests of black-hole physics to advances in quantum technologies, we’re advancing science for generations to come.
Black holes were once invisible to us – until scientists at Cardiff University helped reveal their collisions through gravitational waves.
When LIGO detected the first gravitational-wave signal in 2015, our theoretical, modelling, and data-analysis research was central to identifying the event and extracting its physical properties.
The algorithms, software frameworks, and waveform models developed here have since become foundational tools for the entire field.
A decade later, gravitational-wave astronomy has become a precision science.
Through our leadership roles in the LIGO-Virgo-KAGRA (LVK) collaboration, our researchers now contribute to every stage of the process: from modelling the dynamics of compact binaries to designing the signal-processing methods that detect and interpret them.
With the detectors reaching new levels of sensitivity, the LVK network is observing multiple black-hole mergers each week, enabling a scale of population studies that was once unimaginable.
Shaping discovery
We are leading the next generation of gravitational-wave science – advancing theory, technology, and observation.
From revealing black-hole collisions to building quantum-enhanced instruments and preparing for future space-based detectors, our research is transforming how we understand the universe.
Today’s research. Tomorrow’s world.
-
First detection
Cardiff researchers helped enable the first-ever detection of gravitational waves, developing the models and algorithms that revealed two black holes merging over a billion years ago. -
New signals
Today, we observe several mergers a week through the LVK network – uncovering unexpected black-hole populations and testing Einstein’s predictions under extreme conditions. -
Novel technologies
Our teams are developing the quantum technologies, electronics and precision systems that make LIGO the most sensitive scientific instrument ever built. -
Next frontier
Cardiff researchers are contributing modelling and theory for the next generation of space-based gravitational-wave detectors, set to observe black-hole mergers across the entire Universe.
“The scale and clarity of today’s detections are transforming gravitational-wave astronomy into a precision science, opening entirely new regimes of black-hole physics.”
Professor Stephen Fairhurst, LIGO Scientific Collaboration Spokesperson
Cardiff’s contributions extend well beyond analysis. The University is a major hub for advancing the technologies that make next-generation observations possible.
Experimental teams are developing quantum-enhanced measurement systems, ultra-low-noise electronics and interferometer components that directly inform LIGO’s most sensitive instrument configurations.
Much of this innovation feeds into the upgrades responsible for the dramatic improvement in signal clarity seen over the past decade – progress that now allows researchers to probe black holes in regimes previously accessible only through theory.
This combination of theory, modelling, experiment and systems engineering is shaping the future of the field. Cardiff researchers are already preparing for the next generation of detectors, including the European Space Agency’s LISA mission.
Operating in space rather than on Earth, LISA will observe gravitational-wave signals across the entire Universe, capturing low-frequency mergers and extreme-mass-ratio inspirals that ground-based detectors cannot access.
Cardiff teams are contributing to the mission’s theoretical frameworks, signal models and data-analysis pipelines, laying the groundwork for discoveries that will redefine our understanding of black-hole growth, galaxy formation and the physics of strong gravity.
As gravitational-wave astronomy enters its second decade, Cardiff University remains at the forefront – advancing the science, technology and methods that allow us to measure and interpret the deepest structures of space-time.
Through this work, we are shaping a future in which gravitational-wave observations become as fundamental to astrophysics as electromagnetic astronomy is today.
