It is crucial to understand how particles get energized to non-thermal energies as well as to describe their motion from the sources to an observer or to another location in the universe. Here I summarize some essential, basic aspects of the theory and discuss some topics in the theoretical framework that are currently being developed. I will also discuss some simple applications of the theory of transport to particle acceleration and propagation in the Galaxy.", "revisions": [ { "version": "v1", "updated": "2023-07-21T15:19:02.000Z" } ], "analyses": { "keywords": [ "cosmic ray transport", "charged particles", "cosmic magnetic fields", "distant active galaxies", "non-thermal phenomena" ], "note": { "typesetting": "TeX", "pages": 51, "language": "en", "license": "arXiv", "status": "editable" } } }
