Virialized halos of cold dark matter generically exhibit multi-stream structures accreted within an outermost radial caustic known as the splashback radius. By tracking particle trajectories that accrete onto in cosmological $N$-body simulations, we count their number apocenter passages ($p$), and use them to characterize structure particles. We find density profile for each stream, classified ...

A special technique in heavy metal music utilizes dramatic shifts between loud and soft passages.
