Introducción: En Cusco existe información sobre concentraciones residenciales de radón, pero es limitada la evidencia que integre espacialmente con la incidencia de cáncer de pulmón y las unidades geológicas.
Objetivo: Explorar la relación del radón, cáncer de pulmón y las unidades geológicas en cinco distritos de Cusco.
Materiales y métodos: Se realizó un estudio observacional ecológico...
Lyman-alpha observations are widely used to study hydrogen exospheres. At high altitudes, measured intensity can often be approximated as proportional to hydrogen density integrated along the line of sight. At lower altitudes, the exosphere becomes optically thick, and absorption and multiple scattering produce a nonlocal relation between density and observed intensity. Full radiative-transfer...
This work investigates the cosmological propagation of ultra-high-energy cosmic-ray (UHECR) protons and the associated production of cosmogenic neutrinos. We model the interaction of UHECRs with the cosmic microwave background (CMB) and the extragalactic background light (EBL), including adiabatic energy losses, electron–positron pair production, and photopion production. A Python-based...
