Talk Title and Abstract:

A Spin on Wave Dark Matter

Can the intrinsic spin of light dark matter manifest itself on macroscopic/astrophysical scales? I will first show that the non-relativistic limit, bosonic spin-s dark fields are described by a 2s+1 component Schrodinger-Poisson (SP) system. This can be very useful in numerically simulating structure formation in higher-spin dark matter. I will then show that in this multi-component SP system, there exist solitons with macrosopic spin. Such solitons can reveal their intrinsic spin via gravitational and non-gravitational interactions. I will also discuss vector oscillons resulting from self-interactions in the dark fields, as well as their formation mechanisms.
