  These lectures, presented at TASI 2016: Anticipating the Next Discoveries in
Particle Physics, provide an introduction to some key methods and tools of
indirect dark matter searches. Topics covered include estimation of dark matter
signals, thermal freezeout and related scenarios, potential effects of dark
matter annihilation on the early universe, modeling photon signals from
annihilation or decay, and a brief and qualitative introduction to diffusive
propagation of cosmic rays. The second half of the notes gives a status report
(circa summer 2016) on selected experimental searches, the resulting
constraints and some potential signal candidates. These notes are intended as
an introduction to indirect dark matter searches for graduate students,
focusing on back-of-the-envelope estimates and useful concepts rather than
detailed quantitative computations.
