Description
When bosonic dark matter is sufficiently light, wave-dynamical effects can manifest on astrophysical and even cosmological scales. I will review a range of such phenomena across both linear and nonlinear regimes, including enhancements and suppressions in the density power spectrum, wave interference, soliton formation, and in some cases, generation of macroscopic spin angular momentum density. I will then discuss observational avenues to detect or constrain these effects, and how they can shed light on the the fundamentail properties of these dark fields (number, mass, spin etc), and their cosmological production mechanisms.
