The Institute of Astronomy is the largest of the three astronomy departments in the University of Cambridge, and one of the largest astronomy sites in the UK. Around 180 academics, postdocs, visitors and assistant staff work at the department.Research at the department is made in a number of scientific areas, including exoplanets, stars, star clusters, cosmology, gravitational-wave astronomy, the high-redshift universe, AGN, galaxies and galaxy clusters. This is a mixture of observational astronomy, over the entire electromagnetic spectrum, computational theoretical astronomy, and analytic theoretical research.
The Kavli Institute for Cosmology is also located on the department site. This Institute has an emphasis on The Universe at High Redshifts. The Cavendish Astrophysics Group are based in the Battcock Centre, a building in the same grounds.
