Exploring the makeup of the universe

Our research covers galaxies and stars, large-scale structures, gravitational waves and dark energy

At the Institute of Cosmology and Gravitation (ICG), our Cosmology and Astrophysics research investigates the evolution of galaxies and their stars, the early universe and large-scale structure in the cosmos, as well as the energy content of the Universe and the nature of gravity.

International collaborations

Our scientists play leading roles in major international collaborations, including the Sloan Digital Sky Survey (SDSS), the Dark Energy Survey (DES) and the Laser Interferometer Gravitational-wave Observatory (LIGO), as well as upcoming surveys including the Large Synoptic Survey Telescope (LSST) and the European Space Agency Euclid satellite.


We're committed to inspiring the next generation of scientists through our programme of outreach and public engagement, working with local schools and online communities through citizen science projects.  

We're innovating by developing advanced techniques in data science, analysis and inference for astrophysical, medical and societal applications.


Research at ICG is supported by major national and international funding bodies including:

  • Science and Technology Facilities Council
  • Royal Society
  • European Research Council (ERC)

Our Cosmology and Astrophysics research covers these 4 areas of expertise:


Researchers at the ICG are problem solvers, gaining an understanding of the science of the universe through the analysis of large datasets. Some of our leading scientists teach on our undergraduate and postgraduate maths and physics degree courses.
