Question

`Active galactic nuclei can produce electromagnetic radiation from low-frequency radio wavelengths to high-frequency X-ray wavelengths. Some of this radiation comes from "thermal" sources involving material that has been heated to some characteristic temperature. Other radiation comes from "nonthermal" sources involving charged particles spiraling around magnetic field lines at speeds close to the speed of light. Here, the radiation that is emitted has nothing to do with the temperature of the source. Scientists have been able to reproduce this latter type of radiation in particle accelerators known as synchrotrons. For this reason, nonthermal radiation is often called "synchrotron radiation." Identify which emission properties relate to thermal and synchrotron (nonthermal) radiation

Answer 1

The property of this thermal synchrotron is the Comptonization effect.

Step-by-step explanation:

The high-energy radiation from compact astrophysical objects is emitted by relativistic or semirelativistic thermal and nonthermal leptons (electrons and pairs) via synchrotron, bremsstrahlung, and Compton processes, plus bound-bound and bound-free transitions of high-Z elements. Since Compton scattering is a dominant radiation mechanism in this regime, the most efficient and accurate method to model the transport of high-energy radiation is the Monte Carlo (MC) technique.
