abstract = {We point out that current and planned telescopes have the
potential of probing annihilating Dark Matter (DM) with a
mass of O(100) TeV and beyond. As a target for such
searches, we propose models where DM annihilates into
lighter mediators, themselves decaying into Standard Model
(SM) particles. These models allow to reliably compute the
energy spectra of the SM final states, and to naturally
evade the unitarity bound on the DM mass. Indeed, long-lived
mediators may cause an early matter-dominated phase in the
evolution of the Universe and, upon decaying, dilute the
density of preexisting relics thus allowing for very large
DM masses. We compute this dilution in detail and provide
results in a ready-to-use form. Considering for concreteness
a model of dark U(1) DM, we then study both dilution and the
signals at various high energy telescopes observing γ rays,
neutrinos and charged cosmic rays. This study enriches the
physics case of these experiments, and opens a new
observational window on heavy new physics sectors.},
