A spin on wave dark matter

Can we infer the spin of dark matter from astrophysical observations?  I will talk about the  phenomenology of light vector (or other higher spin) dark matter including (i) interference patterns in mass density (ii) a new class of polarized solitons with macroscopic intrinsic spin.  These effects, along with initial conditions, lead to signals in astrophysics that can potentially distinguish higher spin dark matter from their scalar counterpart (via substructure in halos, dynamical heating of stars, electromagnetic signatures, etc.).  Time permitting, I will provide an argument for a lower bound on the mass of bosonic dark matter.
