Absorption effects on circular repolarization in compact sources. Pacholczyk, A. G. ; Swihart, T. L. Abstract There are known difficulties in attributing the observed circular polarization of compact radio sources to synchrotron emission. Circular repolarization is a plausible alternative: it is consistent with the observed frequency dependence of polarization, with the magnetic field values resulting from synchrotron self-absorption theory, and avoids the known polarization sign-reversal difficulties in the neighborhood of the turnover. Application of the circular repolarization theory leads to the conclusion that the ratio of relativistic to thermal electron density in compact radio sources is between one and 100.
