The Quest for Dark Matter in Astronomical Sources with Cherenkov Telescopes |
|
Abstract |
The problem of dark matter (DM) detection is of paramount importance for modern astrophysics, since it would allow to fully characterize the properties of the ``missing'' mass in the Universe. So far, in fact, the existence of DM is only based on the indirect observations of its gravitational effects on astronomical objects. Efforts to identify plausible DM particle candidates essentially fail without any direct hint about DM physics. Recently, a framework for the astronomical search of DM signals has been arising from the possibility that DM particles self-interact to produce Standard-Model pairs, that subsequently annihilate into final-state gamma photons. The observation of such photons is a task potentially at reach of next-generation Cherenkov telescopes. In this talk, I will illustrate the capabilities of future Cherenkov instruments to detect gamma rays from DM self-interaction by observing low-background, DM-dominated astronomical objects such as the dwarf spheroidal galaxies (dSphs). |
