CINECA IRIS Institutional Research Information System
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Torino.
AperTO è l'archivio istituzionale Open Access destinato a raccogliere, rendere visibile e conservare la produzione scientifica dell'Università degli Studi di Torino.
EnglishParticle dark matter is under deep scrutiny in both direct and indirect searches. An extensive, complex and interrelated network of astrophysical signals, which cover the whole electromagnetic spectrum (from radio to gamma rays) and comprise exotic components in cosmic rays (positrons, antiprotons, antideuterons) is exploited in order to identify a non-gravitational signal of dark matter, able to pinpoint its particle physics nature. Among the various possibilities, this short note discusses a recent proposal: the cross-correlation of the gamma-rays signal with weak gravitational lensing observables, specifically the small distortion of background galaxies measured by the cosmic shear.
