Abstract: | The motion and radiation of a classical electron in a conformally flat Robertson–Walker space, which corresponds to the quasi-Euclidean model of a radiation-dominated universe, is considered. The spectral-angular distribution of the energy radiated by the electron is found; the dependence of the spectrum on the momentum of the electron is investigated; estimates for the coherence interval are given. The results obtained show that the radiation spectrum of a classical electron coincides with the quasiclassical limit of the spectral distribution of the photons radiated by a Dirac electron moving in a radiation-dominated universe. |
