  The indirect detection of dark matter annihilation and decay using
observations of photons, charged cosmic rays, and neutrinos offers a promising
means of identifying the particle nature of this elusive component of the
universe. The last decade has seen substantial advances in observational data
sets, complemented by new insights from numerical simulations, which together
have enabled for the first time strong constraints on dark matter particle
models, and have revealed several intriguing hints of possible signals. This
review provides an introduction to indirect detection methods and an overview
of recent results in the field.
