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.

30th Texas Symposium on Relativistic Astrophysics

The 30th Texas Symposium on Relativistic Astrophysics will take place from Sunday 15 to Friday 20 December 2019 in the historic seaside city of Portsmouth, UK, hosted by the University of Portsmouth’s Institute of Cosmology and Gravitation (ICG).

The Texas meetings have covered topics such as black holes, gravitational waves, neutron stars, cosmic rays, dark matter and the early Universe since the first symposium, held in Dallas in 1963. Following the tradition of previous meetings, the 2019 Symposium will cover a broad range of subjects in relativistic astrophysics.

For full details please visit the Texas 2019 conference website.


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:


Some of our leading scientists teach on our undergraduate and postgraduate maths and physics degree courses.
