Discovering dark matter is one of today's biggest challenges of particle physics
and cosmology. In particular, indirect dark matter detection aims to
discriminate the flux of final stable particles — gamma rays, charged cosmic
rays and neutrinos — produced by particle dark matter annihilation or decay
from the dominant background induced by astrophysical processes.
One of the key elements is the interplay between the theoretically expected dark
matter signal (flux and angular signatures) and astrophysical backgrounds.
I will present the state of the art of searches for dark matter, focusing in particular
on gamma-ray signals from Mev to TeV energies,
I will also discuss future perspectives and avenues for indirect dark matter
detection.
