Abstract: Abstract:
The evolution of cold dark matter in phase-space inevitably leads to high
density regions in physical space, known as caustics. The significance of
these high density structures is a current topic of debate. One
interesting possibility is presented by the caustic ring model, which
describes the accretion of dark matter onto galactic halos. I explain the
formation of dark matter caustics, present an overview of the caustic ring
model and predictions of the model for the Milky Way halo. The resulting
dark matter flows and overdensities may have important consequences for
both direct and indirect dark matter detection experiments.
