Abstract

Multimessenger astronomy is a growing field of research that involves the detection and analysis of different types of cosmic messages, such as gamma rays, cosmic rays, neutrinos, and gravitational waves, with the goal of gaining a more complete and detailed understanding of astrophysical events. The propagation of cosmic rays is an important aspect of this field, as these high-energy charged particles originate from astrophysical sources such as supernovae, stellar remnants, black holes, and pulsars, traveling through interstellar space until they reach Earth. Analysis and simulation software play a crucial role in multimessenger astronomy, allowing researchers to model and understand the physical processes involved in the propagation of cosmic rays and their interactions with the interstellar medium. These tools can simulate the trajectories of particles, the effects of collisions with other particles or magnetic fields, radiation production, and the detection of these particles at ground-based or space-based observatories. In this project, sources of multimessenger particles will be investigated using the CRPropa and gammapy software, aiming to enhance the understanding of particle acceleration processes at the source and their interactions during propagation.
