Invited talk Alternatives to LambdaCDM Cosmology

Description

I will review attempts to address the small-scale problems of Lambda-CDM using a combination of dark matter self-interactions and dark matter interactions with a dark radiation-like species. We will see that most models are rather tightly constrained. New results outlining the role of non-perturbative corrections to these interactions will be presented.
