Abstract

Cosmic rays (CRs) are high-energy particles; bare atomic nuclei, with varying origins and energy levels. Research in this field is focused on identifying potential origins, understanding transport mechanisms faced on their journey to Earth, and interpreting the angular structure of incident CRs. One obstacle of this research is the trajectory modulation induced by the heliosphere during the CRs’ journey. In this work we employ a method to reconstruct the properties of CRs as they were at the local interstellar medium (LISM) by means of a nonlinear model fit to the map at Earth. Another obstacle is the time-averaging used to collect this data, which eliminates latitudinal sensitivity of measurements.
