Laboratory of Astrophysics

Welcome

The Laboratory of Astrophysics (LASTRO) at the EPFL covers a wide range of complementary expertise, with a focus on advanced research and high-quality education of the next generation of astronomers.

With a presence at two locations, the EPFL campus in Lausanne and the Astronomical Observatory at Sauverny near Geneva, the research team at LASTRO takes a leading role in various international consortiums and projects focused on extragalactic astrophysics and observational cosmology.

Euclid space cosmology mission received a 3rd SNSF Sinergia grants

— Prof. Frédéric Courbin (LASTRO) associated with CIS was allocated, for the 3rd time in a row, a SNSF sinergia grant related to the ESA-NASA Euclid space mission. The grant, to be shared between EPFL (PI), UniGE, UniZH and FHNW will allow to finalize the preparation of the satellite, to be launched by the end of 2022, and will enable the exploitation of the very first data to come.

Astrophysicists fill gaps in the history of the Universe

— An international consortium of scientists has analyzed, as part of a vast program of cosmological surveys, several million galaxies and quasars, thus retracing a more continuous history of the Universe and offering a better understanding of the mechanisms of its expansion. The latest 6 year-long survey called eBOSS was initiated, and led in part, by EPFL astrophysicist Jean-Paul Kneib.

EPFL joins the giant radio telescope SKA for the Swiss community

— The Square Kilometre Array, or SKA, will be the biggest radio telescope ever built. Thanks to this ambitious tool, some of the universe’s greatest mysteries will be resolved. EPFL became a member of the SKA Organisation (SKAO) beginning of April 2020 and will coordinate the contributions to this project on behalf of the Swiss academic community.

Cosmic magnifying glasses show faster expanding universe

— New measurements using gravitational lensing, an innovative method that EPFL researchers have been working on for many years, suggest the universe is expanding faster than previously thought.
