Organisation profile
The Institute of Cosmology and Gravitation (ICG) is an international centre of research excellence in cosmology, gravitation and astrophysics.
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. Through the work of the institute, we seek to understand the physics of the Universe and inspire the next generation of scientist. We also innovate using our advanced skills in mathematics and data science.
Scientists at the ICG play leading roles in major ongoing international collaborations and projects, including the Sloan Digital Sky Survey (SDSS), the Large Synoptic Survey Telescope (LSST), the European Space Agency Euclid satellite, the Laser Interferometer Gravitational-wave Observatory (LIGO) and the Laser Interferometer Space Antenna (LISA).
Research at the Institute covers theoretical and observational cosmology and astrophysics, and their interface, and is supported by Science and Technology Facilities Council (STFC), Royal Society, European Research Council (ERC) and European Union (EU) funding.
Our work covers topics including the very early universe, dark energy, testing gravity on cosmological scales, large scale structure, gravitational lensing. supernovae, galaxy evolution, and stellar population modelling.
Our areas of expertise are:
- Astrophysics
- Observational cosmology
- Theoretical cosmology
- Gravitational waves
UN Sustainable Development Goals
In 2015, UN member states agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. Our work contributes towards the following SDG(s):
