The Self-Interacting Dark Matter Paradigm

by Dr Haibo Yu (U.C. Riverside)

The ΛCDM model has been remarkably successful in explaining the large scale structure of the Universe, but it fails to accommodate the observations on galactic scales. In this talk, I will review recent developments of a new dark matter theory, self-interacting dark matter(SIDM). I will show that SIDM can pr! ovide a consistent solution to the small-scale issues across all scales, even though individual systems exhibit a wide diversity in their properties.
