DESI shakes up the dark Universe - an overview
ORAL · Invited
Abstract
Dark Energy, which makes up 70% of the Universe and is responsible for its accelerated expansion, is the biggest mystery in cosmology. The Dark Energy Spectroscopic Instrument (DESI) is on its way to building the largest 3D map of the Universe to address this question. I will present the DESI survey, give an overview of the DESI first-year BAO results and discuss the intriguing varying dark-energy they hinted at. I will then provide a brief introduction of the new DESI results.
