Polarization Angle Geodesics in PSRs B1133+16 and B2016+28
M. M. McKinnon
Recent models of pulsar polarization predict that the position and ellipticity angles of the polarization vector can trace portions of a small or great circle on the Poincare spher…
Statistical Properties of a Polarization Vector's Ellipticity Angle
M. M. McKinnon
The orientation of a polarization vector on the Poincare sphere is defined by its position angle (PA) and ellipticity angle (EA). The radio emission from pulsars, magnetars, and fa…
Polarization Estimation for Radio Pulsars
M. M. McKinnon
A number of polarization estimators have been developed for a variety of astrophysical applications to compensate measurements of linear polarization for a bias contributed by the…
Unusual intra-burst variations of polarization states in FRB 20210912A and FRB 20230708A : Effects of plasma birefringence?
Apurba Bera, Clancy W. James, Mark M. McKinnon +6
Fast radio bursts (FRBs) are highly energetic events of short-duration intense radio emission, the origin of which remains elusive till date. Polarization of the FRB signals carry…
Behavior of the Position and Ellipticity Angles at Polarization Mode Transitions in Pulsar Radio Emission
M. M. McKinnon
Polarization observations of radio pulsars show that abrupt transitions in the polarization vector's position angle can be accompanied by large excursions in the vector's elliptici…
