Anatomy of an extensive air shower: building an optimal radio emission calculation

Juan Ammerman-Yebra, Harm Schoorlemmer

Radio emission from particle air showers is one of the most promising detection techniques to achieve an experiment with a large exposure in ultra-high-energy astroparticle physics…

Simulating an imaging atmospheric radio telescope to observe cosmic gamma rays and cosmic neutrinos

Sebastian Achim Mueller, Anne Timmermans, Juan Ammerman-Yebra +1

Observations of cosmic gamma~rays with energies above the 10 electronvolts (TeV) regime are often a direct probe of events where our theoretical predictions are challenged b…

Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346

Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…

Search for active-sterile neutrino transitions using Pierre Auger Observatory data

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +348

We investigate the sensitivity of the Pierre Auger Observatory to physics beyond the Standard Model arising from magnetic-moment-induced transitions between active and heavy steril…

Proton-air interaction properties at TeV from shower-depth measurements with the Pierre Auger Observatory and their connection to the Muon Puzzle

The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +347

Hybrid measurements at the Pierre Auger Observatory indicate that most high-energy hadronic interaction models underestimate the average depth of the shower maximum, $\langle X_{\m…

Imaging the radio-wave emission from extensive air showers

Juan Ammerman-Yebra, Harm Schoorlemmer, Anne Timmermans +1

We propose a new way to observe cosmic-ray-induced air showers by imaging the radio emission. With simulations we demonstrate key features for imaging the radio-wave emission from…
