A comprehensive 3D numerical model simulates the modulation of galactic deuterons from 2006 to 2022.
Observations from AMS-02 reveal galactic deuteron spectral features over a rigidity range from 1.92 GV to 19.5 GV.
The study integrates diffusion and drift coefficients to challenge established paradigms of galactic deuteron origins.
Comparisons are made between the model outputs and actual detector data from PAMELA and AMS-02 for validation.

This analysis simulates galactic deuterons' modulation using a 3D model, comparing results with AMS-02 and PAMELA observations.

Ramokgaba et al. (2025) studied this question.
