The Fundação para a Ciência e Tecnologia (FCT) and the French Ministère de l'Enseignement supérieur, de la Recherche et de l'Innovation (MESRI) announced the results of the Programme for Cooperation in Science between Portugal and France for the 2022-2023 period.
The main goal of the ADIEU project is to investigate the generic implications of dark energy-dark matter interactions in the early Universe. By considering a scalar-tensor framework involving conformal and disformal couplings, the team will aim to construct a general family of coupled quintessence models leading to scaling solutions during radiation domination and able to enhance the growth of perturbations prior to matter-radiation equality. Aspects such as virialization and potential emission of gravitational waves by the resulting structures will be considered.
