The scope of our research is as wide as the cosmos we explore. Thanks to our affiliation with the UK ATC and our strong links with related research centres in the School of Physics and Astronomy, we are in a rare position to accommodate a diversity of research specialisms. Our current areas of research include: cosmology (large-scale structure in the universe, galaxy formation, dark matter and dark energy); active galactic nuclei and related objects; nearby galaxies (large-scale star formation, structure, content and evolution of galaxies); stellar astronomy (parallax and proper motion studies, the stellar luminosity function, symbiotic stars); star formation (observation and theoretical studies, star formation in external galaxies); planet formation (disc and planet formation in protostars, discs around pre-main-sequence stars); computational astrophysics (through the Edinburgh Centre for Computational Astrophysics).
