CREDO: the first NATM >= 1 observatory This talk Cosmic Ray Extremely Distributed Observatory Status March 2016: an idea DATABASE/ INTERFACE Central database/interface: access to everything for everybody 4
State of the art detection of cosmic rays: NATM = 1 6
Generalized detection of cosmic rays: NATM >= 1 UHECR (p, Fe) UHECR ( γ cascade) NATM = 1 NATM > 1 cascade NATM = 1 ATMOSPHERE NATM > 1 GROUND STATISTICS SIGNATURES CHANCE FOR A UNIQUE SIGNATURE! : a cosmic ray detector 7

Motivation: Lorentz Invariance Violation Modified dispersion relation of a photon: limits from gamma ray astronomy, 98% C.L. (Klinkhamer & Schreck, 2008): 6 x 10 20 > κ > 9 x 10 16 γ UHE κ > 0: pair production supressed more UHE photons reach Earth e e+ γ UHE γ UHE e+ κ = 0: normal pair production e e+ e κ < 0: pair production enhanced (photon lifetime ~ 1 sec.!) no UHE photons reach Earth critical importance for the UHE photon search! Observation of photon cascades would point to κ < 0! 12
Motivation: Experimental Quantum Gravity T. Jacobson, S. Liberati, and D. Mattingly, Annals Phys. 321 (2006) 150 PH: Gamma Ray Bursts & time delays (spacetime foam)! 13
Motivation: Novel Experimental Quantum Gravity PH: Gamma Ray Bursts & time delays 1D approach to spacetime foam! CREDO: 3D approach with ECR 14
