Leading research and education of all aspects of astrophysics and cosmology, including dark energy & dark matter, galaxy evolution, and cosmological parameters. Our research activities attempt to answer some of the many questions relating to the evolution of first stars and galaxies, dwarf galaxies, large scale structures, and galaxies in the cosmic web. The Laboratory of Astrophysics is split between the EPFL Campus in Lausanne, and the Sauverny Observatory in Versoix, near Geneva. It offers dedicated courses in astrophysics and cosmology both on the EPFL campus and online via a recently launched MOOC https://www.edx.org/course/introduction-a-lastrophysique-2.
