Nongravitational interactions between dark matter particles can impact the structure of dark matter halos to solve the longstanding core/cusp problem for galactic rotation curves. Here I discuss new work aimed at constraining these effects on complementary scales. These include galaxy groups and clusters, on the larger side, and subhalos in within the Milky Way on the smaller side.
