Astroparticle physics with H.E.S.S.: dark matter and Lorentz invariance violation studies.
E. Moulin
H.E.S.S. is an array of four imaging atmospheric Cherenkov telescopes detecting γ rays in the very high energy (Eγ >100 GeV) domain. The astroparticle physics program with HESS includes the search for dark matter and the study of possible Lorentz invariance violation. I will review latest results on both topics.
