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. https://www.pomyslnaszycie.com/white-and-green-bulletin-board-border-simply-boho-schoolgirl-style-on-sale/
