Open AccessObservation of seasonal variations of the flux of high-energy atmospheric neutrinos with IceCube
Atmospheric muon neutrinos are produced by meson decays in cosmic-ray-induced air showers. The flux depends on meteorological quantities such as the air temperature, which affects the density of air. Competiti...

Open AccessDetection of astrophysical tau neutrino candidates in IceCube
High-energy tau neutrinos are rarely produced in atmospheric cosmic-ray showers or at cosmic particle accelerators, but are expected to emerge during neutrino propagation over cosmic distances due to flavor mi...

Open AccessLow energy event reconstruction in IceCube DeepCore
The reconstruction of event-level information, such as the direction or energy of a neutrino interacting in IceCube DeepCore, is a crucial ingredient to many physics analyses. Algorithms to extract this high l...

Open AccessThe energy spectrum of cosmic rays beyond the turn-down around \(\varvec{10^{17}}\) eV as measured with the surface detector of the Pierre Auger Observatory
We present a measurement of the cosmic-ray spectrum above 100 PeV using the part of the surface detector of the Pierre Auger Observatory that has a spacing of 750 m. An inflection of the spectrum is observed, ...

Open AccessVelocity independent constraints on spin-dependent DM-nucleon interactions from IceCube and PICO
Adopting the Standard Halo Model (SHM) of an isotropic Maxwellian velocity distribution for dark matter (DM) particles in the Galaxy, the most stringent current constraints on their spin-dependent scattering c...

Open AccessDirect measurement of the muonic content of extensive air showers between \(\mathbf { 2\times 10^{17}}\) and \(\mathbf {2\times 10^{18}}~\)eV at the Pierre Auger Observatory
The hybrid design of the Pierre Auger Observatory allows for the measurement of the properties of extensive air showers initiated by ultra-high energy cosmic rays with unprecedented precision. By using an arra...

Reconstruction of energy spectra of elemental groups with KASCADE: Sensitivity to hadronic interaction models
The electron and muon number of extensive air showers (EAS) measured at ground level are the main observables of the detector array of the KASCADE experiment. The two-dimensional frequency distribution of thes...

Tests of hadronic interaction models by data of the KASCADE-Grande air-shower experiment
KASCADE-Grande is a multi-detector setup to get redundant information on single air shower basis. The information is used to perform multi-parameter analyses to solve the threefold problem of the reconstructio...
