Motivations for self-interacting dark matter models and their viable signatures

In this talk, I will motivate the idea that dark matter particles may interact with each other strongly and describe how adding self-interactions modifies galaxies, leading to constraints and preferred regions of parameter space. In these preferred regions, self-interactions can leave unique imprints in gravitational lensing images and faint galaxies, which could be observed soon.
