Radio-detection of neutrino-induced air showers: the influence of topography

Understand

Neutrinos of astrophysical origin could be detected through the electromagnetic radiation of the particle showers induced in the atmosphere by their interaction in the Earth.

• This applies in particular for tau neutrinos of energies $E>10^{16}$eV following Earth-skimming trajectories.
• The $\sim1^{\circ}$ beaming of the radio emission in the forward direction however implies that the radio signal will likely fly above a detector deployed over a flat site and would therefore not be detected.
• We study here how a non-flat detector topography can improve the detection probability of these neutrino-induced air showers.
