Scientic Program DARKMOD

Topic

The acceleration of the expansion of the Universe at low redshifts has not received a satisfactory theoretical explanation yet. The value of a possible cosmological constant remains a puzzle and alternative approaches, dark energy or modified gravity, are still being developed. In view of the future observations by galaxy surveys, such as EUCLID for instance, it is timely to gather experts on both the theoretical aspects of dark energy and modified gravity, together with phenomenologists and observers.  

This 4-week workshop will provide an opportunity to discuss most aspects of both dark energy and modified gravity, from their theoretical construction to their link with observational cosmology.

Format:

During the weeks 1, 2 and 4, there will  be typically 1-2 lectures and/or 1-2 talks per day. There will be ample time for discussions to favour new collaborations.

During the week 3, there will be a one-week conference, on dark energy and modified gravity.

Although the focus may slightly vary with the week, the program remains centered on the dark-energy and modified-gravity issues. To facilitate collaborations and discussions between nearby topics, from observations to theory, we encourage participants to attend the workshop for 2 weeks.
