On the Electron Energy Distribution in Jets, Hotspots and Lobes of Extragalactic Radio Sources

Abstract

Understanding of extragalactic radio sources requires understanding of their multiwavelength emission, and thus evolution of the radiating ultrarelativistic electrons. Unfortunately, many of the key issues regarding particle acceleration and generation of the non-thermal radiation in relativistic jets, their hotspots and lobes, are still hardly known. Here I will review some of the new results concerning these problems. In particular, I will discuss how an interplay between theoretical studies and the most recent multifrequency observations allow for constraining acceleration and radiative processes taking place in extragalctic radio sources, and thus for extracting crucial parameters of the considered objects. I will emphasize that in many aspects these new results contradict/question standard models, assumptions and expectations. Paradigm of the diffusive shock acceleration and the resulting universal power-law form of the radiating electrons are the two examples of the challenged issues.
