Micro-physics of Cosmic-Ray Observables (MiCRO)

MiCRO is a 4-years research project funded by the French National Research Agency ("ANR"). The goals of the project are to improve theoretical models of cosmic-ray (CR) transport in the Galaxy based on the micro-physics of CR-turbulence interaction, and to pinpoint how these different models relfect onto the associated multi-messenger and multi-wavelength observables (i.e., direct detection of cosmic rays, gamma-ray and radio emission, neutrino fluxes).

MiCRO's key scientific question:

• How we model different type of plasma turbulence (both pre-existing and CR-generated), and how we self-consistently describe CR-transport considering these different models?

• What specific signatures belonging to these different scenarios can be found and/or predicted in the context of direct and indirect CR data from current and forthcoming experiments?
