Description

Dark Universe Cosmology

Description

The dark sector of our Universe is still a vastly unexplore

d territory from both the theoretical and observational point of view. The dynamics of inflation, the nature of dark matter, axion physics, dark energy, cosmic strings and the primordial production of gravitational waves are just some of the most pressing problems. The aim of this workshop is to investigate these aspects at the boundary between string theory, cosmology and fundamental physics. 

Context 

This workshop is supported by the COSMIC WISPers COST Action CA21106. The aim of this Action is to study very weakly interacting slim particles (WISPs) from different perspectives: theory, indirect observational consequences in astrophysics, searches at colliders and direct detection in laboratories.

Accommodation 

A list of suggested hotels with special rates can be found here. When booking, please specify "convenzione INFN".
