Some Aspects of Cosmic Synchrotron Sources,
Abstract
In the earlier treatments of synchrotron theory it was usually assumed that the pitch angles of the radiating particles are of the order of unity and that the emission occurs at high harmonics of the fundamental frequency. In this investigation the authors have examined synchrotron radiation for some of the cases for which these assumptions are not applicable. Considered first is the synchrotron emission from individual particles which have small pitch angles, the general properties of synchrotron sources which mainly contain such particles, and the emissivities and degrees of circular polarization for specific source distributions. Then considered are several models for actual synchrotron sources. The limitation of synchrotron source models for optical pulsars and compact extragalactic objects are discussed and it is shown that several existing models for the pulsar NP 0532 are inconsistent with the measured time variations and polarizations of the optical emission.
