World leading research across a vast range of scales, from the quantum regime to the entire Universe. 

The Southampton Theory Astrophysics and Gravity (STAG) Research Centre brings together three research groups with world-leading expertise on issues relating to fundamental physics and astronomy. STAG researchers are interested in problems ranging from the ultimate building blocks of matter to dynamics on cosmological scales, and actively engage with high-profile international experiments and observational facilities.  STAG runs a regular interdisciplinary seminar series, hosts international visitors and arranges high-profile research colloquia.
