Abstract EN
We discuss the formation of dark matter caustics, and their possible detection by future dark matter experiments.
The annual modulation expected in the recoil rate measured by a dark matter detector is discussed.
We consider the example of dark matter particles with a Maxwell-Boltzmann velocity distribution modified by a cold stream due to a nearby caustic.
It is shown that the effect of the caustic flow is potentially detectable, even when the density enhancement due to the caustic is small.
This makes the annual modulation effect an excellent probe of inner caustics.
We also show that the phase of the annual modulation at low recoil energies does not constrain the particle mass unless the velocity distribution of particles in the solar neighborhood is known.
