Simulation of propagating EAS Cherenkov radiation over the ocean surface

TL;DR

This paper models how Cherenkov light from extensive air showers propagates over the ocean, analyzing detection limits for satellite-based sensors considering ocean surface waves.

Contribution

It provides new computational results on Cherenkov light propagation over water and assesses detection feasibility for satellite instruments like TUS.

Findings

Detection limits depend on shower zenith angles and ocean surface conditions.

Reflected Cherenkov photon flashes are detectable within specific zenith angle ranges.

Ocean waves significantly influence Cherenkov light reflection and detection capabilities.

Abstract

We present computing results of the Cherenkov light propagation in air and water from extensive air showers developing over the ocean. Limits on zenith angles of the showers, at which the registration of flashes of reflected Cherenkov photons by the satellite-based detector TUS is possible, are analyzed with consideration for waves on the ocean surface.
