DΛrk Energy: from Fundamental Theories to Observations (and back)

11 Sept 2023, 09:00 → 15 Sept 2023, 20:00 Europe/Rome

INFN-LNF, Auditorium Bruno Touschek

Enrico Nardi (Istituto Nazionale di Fisica Nucleare)

The Dark Energy from Fundamental Theories to Observations Conference will be held in the Bruno Touschek Auditorium (Bldg. 36, access from LNF secondary entrance in Via E. Fermi, 60 - see map).        (Talks by invitation only)

You are welcome to download the conference poster here.

Aim of the meeting:

The problem of dark energy has unprecedentedly taken a central stage in the gravitation and cosmology research field, also in the view of the discrepancies found in the current expansion of the Universe as derived from Planck data and from local direct measurements. In this regard, we aim at organising an international workshop to discuss dark energy both from the theoretical and observational points of view. The workshop will be a precursor to the growing interest that this topic will gain in the near future due to the Euclid satellite, whose launch is planned for later this year, complementary ground-based observatories and Cosmic Microwave Background data. We would like to gather experts (both from the theory and observational sides) to understand together, through talks and discussion sessions, which predictions of fundamental theories can be tested by observations and, conversely, which new roads in fundamental physics may be opened by the future data. 

Important dates:
