Astrophysicists fill gaps in the history of the Universe

EPFL

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.

Shaking light with sound

Research

Combining integrated photonics and MEMS technology, scientists from EPFL and Purdue University demonstrate monolithic piezoelectric control of integrated optical frequency combs with bulk acoustic waves. The technology opens up integrated ultrafast acousto-optic modulation for demanding applications.

“Even on such a small scale, it feels like we're making a difference”

EPFL

In the middle of the economic crisis caused by the COVID-19 lockdown, Samuel Bosch, EPFL student, and Alexander Sanchez de la Cerda, Computer Science graduate and Vice-President of the EPFL Quantum Computing Association, wanted to make a difference. So they founded a startup that will help create jobs.
