Resumen:
High-energy observatories are continuously enhancing our knowledge ofthe gamma-ray sky, both unveiling new sources and providing a more detailed comprehension of the known ones. Many kinds of astrophysical systems have been found to produce gamma-ray radiation (e.g. supernova remnants, pulsar wind nebulae, active galactic nuclei, etc.). Radiation at very high photon energies requires the existence of relativistic populations of particles, but the source and detailed acceleration mechanisms of these particles are still a matter of debate, and one of the present challenges of relativistic astrophysics. Many scenarios have been developed to explain the gamma-ray emission of different types of sources. As the datasets on gamma-ray sources grow larger, the proper comparison of these scenarios with observations relies in our ability of obtaining accurate predictions from them. The detailed computation of gamma-ray production and transport in astrophysical scenarios becomes then a key issue in the field. In this work we introduce PRINCE, a novel tool developed to describe the gamma-ray emission and propagation in cosmic environments. This tool relies in an ab-initio computation of elementary processes of emission, absorption and scattering of high-energy photons, allowing to compute the production of gamma-rays in lepto-hadronic models, and their propagation in arbitrary matter, radiation, and magnetic fields. We show the application of PRINCE to some outstanding problems, such as gamma-ray emission from microquasars or the propagation of high-energy photons through intergalactic radiation and magnetic fields, and discuss the kind of predictions it can provide beyond those of other techniques.
