Les Houches Lectures on Indirect Detection of Dark Matter
  These lectures, presented at the 2021 Les Houches Summer School on Dark
Matter, provide an introduction to key methods and tools of indirect dark
matter searches, as well as a status report on the field circa summer 2021.
Topics covered include the possible effects of energy injection from dark
matter on the early universe, methods to calculate both the expected energy
distribution and spatial distribution of particles produced by dark matter
interactions, an outline of theoretical models that predict diverse signals in
indirect detection, and a discussion of current constraints and some claimed
anomalies. These notes are intended as an introduction to indirect dark matter
searches for graduate students, focusing primarily on intuition-building
estimates and useful concepts and tools.
