We study the time dependent propagation of sub-ankle ultra high energy cosmic rays (UHECRs) originating from point-like Galactic sources. We show that drift in the Galactic magnetic field (GMF) may play an important role in the propagation of UHECRs and their measured anisotropy, particularly when the transport is anisotropic. To fully account for the discreteness of UHECR sources in space and time, a Monte Carlo method is used to randomly place sources in the Galaxy. The low anisotropy…

Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 × 1018 eV

TLDR
The Pierre Auger Collaboration reports the observation of thousands of cosmic rays with ultrahigh energies of several exa–electron volts, arriving in a slightly dipolar distribution, showing that they originate outside the Milky Way Galaxy.

LIFETIME OF A COSMIC-RAY SPOT

We investigate the existence, angular sizes, and durations of ultrahigh-energy cosmic-ray (UHECR) hotspots as observed at Earth after the UHECRs propagate through the Galactic magnetic field. We show

Indication of a local fog of subankle ultrahigh energy cosmic rays

During their propagation through intergalactic space, ultrahigh energy cosmic rays (UHECRs) interact with the background radiation fields. These interactions give rise to energetic electron/positron

We constrain the energy at which the transition from Galactic to extragalactic cosmic rays occurs by computing the anisotropy at Earth of cosmic rays emitted by Galactic sources. Since the diffusion
