The Workshop aims at brainstorming on the possibility to study the anisotropic properties of the high-energy gamma-ray background by using future gamma-ray telescopes at TeV energies. The goal is to investigate how sensitive the cross-correlation technique between TeV gamma-rays and gravitational tracers of the dark matter distribution in the Universe can be to a signal originated by a multi-TeV-scale dark matter particle. Attention will be paid on identifying the features required by a Cerenkov telescope in order to study the cross-correlation signal. The focus will be on CTA.
