... Kellermann and Pauliny-Toth [5] showed that the maximum brightness temperature that a source can sustain is limited by the cooling due to inverse Compton scattering in the Thomson regime, which rises rapidly when the source exceeds TB > 3 в 1011 K. As pointed out by Crusius-Waetzel [6], brightness temperatures higher than 1012 K can be produced by monoenergetic electron, since the GHz photons can emerge from the source without being absorbed by low energy electrons. ...
