Time-Structured Tail Probabilities for Ultra-High-Energy Gamma-Hadron Discrimination in Water-Cherenkov Arrays
Ruben Conceição, Pedro J. Costa, Mário Pimenta
Gamma-hadron discrimination based on shower observables is essential for identifying gamma-ray astrophysical sources at the highest energies. In this work, we introduce $P^{α, T}_…

The Energy Spectrum of Ultra-High Energy Cosmic Rays across Declinations to as measured at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +360
The energy spectrum of cosmic rays above 2.5 EeV has been measured across the declination range using data from events accrued a…
