96. Radio interferometry applied to the observation of air showers

We developed a Radio Interferometric Technique for the observation of extensive air showers initiated by cosmic particles. This technique leads to a four dimensional representation of the extensive air shower. From this representation shower parameters are reconstructed in a straightforward manner. In this contribution, we show the application on radio simulations of air showers and study the...

106. Expected performance of interferometric air-shower measurements with sparse radio-antenna arrays

Inclined air showers open the window for the radio detection of ultra-high-energy cosmic rays with km-sparse radio-antenna arrays. The potential of those measurements would improve greatly with an accurate reconstruction of the depth of the shower maximum $X_\mathrm{max}$. However, traditional methods using the lateral signal amplitude distribution at the ground to reconstruct $X_\mathrm{max}$...

124. New features in the radio-emission of very inclined showers

To probe the sources of ultra-high energy cosmic-rays, next generation of radio experiments such as GRAND and AugerPrime Radio are now focusing on the detection of showers arriving with very inclined trajectories. These inclined showers have a large footprint that allows us to cover large surfaces at low costs, but their radio emission exhibits numerous features that differentiate them from...

102. Parameterization of the frequency spectrum in the 30-80 MHz of radio emission from inclined air showers

Martinelli, Sara

The frequency spectrum of the short transient radio pulses from air showers contains valuable information. Its shape depends on several factors, most importantly on the lateral distance of the observer from the shower axis, the arrival direction, i.e. the zenith angle, and on the distance between core position and shower maximum $X_{\mathrm{max}}$. To exploit this wealth of information, we...

105. Signal model and event reconstruction for the radio detection of inclined air showers using sparse antenna arrays

Schlüter, Felix (Karlsruhe Institute of Technology - Institute for Astroparticlephysics)

We present a signal- and reconstruction model for the radio emission of extensive air showers with zenith angles between 65$^\circ$ and 85$^\circ$ in the 30-80 MHz band. The model is derived from CoREAS simulations and explicitly takes into account the asymmetries introduced by the superposition of charge-excess and geomagnetic radiation as well as by early-late effects. We exploit...
