Dark Energy Interactions

1 Oct 2014, 08:00 → 3 Oct 2014, 12:30 Europe/Stockholm

122:026 (Albanova, Stockholm)

David Fonseca Mota (University of Oslo), Tomi Koivisto (Nordita)

The slides for the talks can be found here! . Venue Albanova, Stockholm, Sweden Scope The main theme is dark energy, and even more specifically the possible interactions of dark energy. The emphasis is theoretical but observational prospects shall be discussed with great interest. Some specific topics to be covered are Screening mechanisms : Vainshtein, Chameleon, Disformal, Symmetron. Structure formation : Linear and nonlinear, Dark energy perturbations, Euclid forecasts. Couplings to visible sector : Variations of constants, astrophysical and cosmological constraints. Bimetricity : Ghost-free massive and bimetric gravity, couplings of matter and gravity. Schedule The talks will begin on Wednesday morning and the workshop will end on Friday at lunch time. Some will however stay the whole week for relaxed collaborations.
