Small-Scale Structure in Vector Dark Matter

Abstract: Can we figure out the spin of dark matter from astrophysical observations? I will talk about new phenomenology of (ultra)light vector dark matter including (i) a new class of polarized vector solitons (ii) interference patterns in density (iii) intrinsic spin. I will provide results for nonlinear structure formation in vector dark matter where this phenomenology is naturally present. These effects lead to signals in astrophysics and direct detection that can potentially distinguish vector dark matter from their scalar counterpart. Time permitting, I will discuss the generalization of above phenomenology to higher spin bosonic fields.
