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}_…

Scaler rates from the Pierre Auger Observatory: a new proxy of solar activity
The Pierre Auger Collaboration, I. Bizzarri, C. Dionese +1
The modulation of low-energy galactic cosmic rays reflects interplanetary magnetic field variations and can provide useful information on solar activity. An array of ground-surface…
