On the origin of the ultra-high energy cosmic-rays

The origin of the ultra-high energy cosmic-rays (UHECRs) is still unknown. I will show that the observational data on the spectrum and composition can be explained by a generic model having one Galactic component and one extragalactic component. I will review the constrains brought by neutrino and gamma-ray experiments on UHECR origin. I will also discuss the origin of the UHECR dipole anisotropy recently reported by the Pierre Auger Observatory.
