Description

The Athens symposium on Exploring the Universe (ATHEXIS) will take place οn 10-14 June 2024.

It aims to bring together scientists working on (astro)particle physics and cosmology and initiate cross-field discussions on recent developments and future prospects. The presentations will cover recent progress on theoretical, phenomenological and observational aspects of cutting-edge topic.

This meeting is organized by the National Technical University of Athens, the National Hellenic Research Foundation, University of Cyprus, Instituto de Física Corpuscular - CSIC / University of Valencia, Sorbonne University and École Normale Supérieure.
