Second EuCAPT Annual Symposium
Online only
CERN
The European Consortium for Astroparticle Theory (EuCAPT, https://www.eucapt.org) is a new initiative, with central hub at CERN, that aims to bring together the European community of theoretical astroparticle physicists and cosmologists. Our goals are to increase the exchange of ideas and knowledge; to coordinate scientific and training activities; to help scientists attract adequate resources for their projects; and to promote a stimulating, fair and open environment in which young scientists can thrive.
After a first meeting in 2021 with nearly 900 registered participants, we are delighted to announce the second edition of the EuCAPT annual symposium, the flagship event of our consortium, that aims to provide an interdisciplinary Europe-wide forum to discuss opportunities and challenges in Theoretical Astroparticle Physics and Cosmology. We invite all scientists (PhD students, postdocs, and staff) active in these fields of research to join us remotely from May 23 to May 25, 2022. The symposium will feature invited presentations, and young scientists will have the opportunity to present their work with lightning talks.
