The Laboratory of Astrophysics focuses on reseach in extragalactic astrophysics and observational cosmology. The areas of research include, among other subjects, strong and weak gravitational lensing, quasar host galaxies and black holes, and the formation and evolution of galaxies in the universe, from the closest to the most distant ones.
The Laboratory works closely with the Astronomical Observatory of the University of Geneva. The collaboration constitutes the main center of astrophysics in the French-speaking part of Switzerland, as far as teaching, research, and the scientific outreach to the public are concerned.
The research and teaching activities take place at the EPFL campus (teaching) and at the Observatoire de Sauverny, near Versoix (research and advanced teaching).
