COSMOS meeting on Astroparticle and Fundamental Physics with the CMB

26 Jun 2018, 09:30 → 27 Jun 2018, 16:30 Europe/Rome

C412 (Dipartimento di Fisica e Scienze della Terra - Università degli Studi di Ferrara)

The workshop is devoted to Astroparticle and Fundamental Physics and is part of a series of events organized within the ASI-financed COSMOS network for Cosmic Microwave Background research.

Topics to be discussed include CMB anomalies, neutrino cosmology, parity violations, primordial nucleosynthesis, dark energy and reionization. There will be invited talks by both COSMOS and external colleagues to review the state of the art and theoretical and observational perspectives, also in view of forthcoming experimental probes.
