A UC Irvine Center for Cosmology and UC Riverside collaboration showed strong evidence from the wide diversity of rotation curves of galaxies points to dark matter having self interactions. The results were published in the world’s premier physics letter journal, Physical Review Letters, covered in American Physical Society’s Synopsis, and received broad press coverage including in Physics World. Authors of the paper were Ayuki Kamada, Manoj Kaplinghat, Andrew B. Pace, and Hai-Bo Yu.
