Séminaire de Physique Théorique
Dark matter and alternativesBenoit Famaey (Observatoire Astronomique de Strasbourg)
Thursday 11 June 2026 13:30 - Salle des séminaires - Salle 1180, bâtiment E2
Résumé :
In this talk, I will summarize the missing mass problem at galaxy scales, and will explore the possibility that some of the current most salient challenges of galaxy formation might have a fundamental origin, rather than simply indicate a problem in our understanding of the modeling of baryons within the standard Lambda Cold Dark Matter cosmological model. I will therefore explore how alternatives to Cold Dark Matter can help (or not) to solve some of these riddles, going all the way from warm, mixed, fuzzy or self-interacting dark matter to more radical alternatives such as modified gravity.
