EPFL/CERN/UNIGE Discussion Sessions

Monday 30 Mar 2015, 14:30 → 17:30 Europe/Zurich

Observatoire de Sauverny

To prompt collaboration among the different groups in cosmology in the Léman area, we hold a common discussion session every month and a half. In those, recent news in the field are addressed by experts at a level that we can all understand. Please, suggest papers/subjects to the local organizers. The suggested papers for this session are:
