Cascades initiated by EHE photons in the magnetic field of the Earth and the Sun
The content of extremely high energy (EHE) photons in the highest energy cosmic rays can be investigated by analyzing showers arriving from directions where the perpendicular component of the Earth’s magnetic field is high or showers arriving from the region surrounding the Sun. We perform Monte Car...
