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://ashleyshomestores.shop/product-category/6-piece-sectional-with-chaise-2/
