Description

Air-Shower Universality is a framework that describes the regularity in the longitudinal, lateral, and energy distributions of electromagnetic shower particles, motivated by solutions to the cascade equations. We employ a universality-based model of shower development that incorporates hadronic particle components to reconstruct observables from extensive air showers produced by ultra-high-energy cosmic rays. The model can estimate key parameters, such as the depth of shower maximum ($X_\text{max}$) and the number of muons ($N_\mu$) at the event level, depending on the input parameters. We present the performance of the reconstruction algorithm using both air-shower simulations, and data from the Pierre Auger Observatory.
