Polarization Measurements of Arecibo-Sky Pulsars: Faraday Rotations and Emission-Beam Analyses

We present Faraday Rotation Measure (RM) values derived at L- and P-band as well as some 60 Stokes-parameter profiles, both determined from our longstanding Arecibo dual-frequency pulsar polarimetry programs. Many of the RM measurements were carried out toward the inner Galaxy and the Anticenter on...

Zusammenfassung:We present Faraday Rotation Measure (RM) values derived at L- and P-band as well as some 60 Stokes-parameter profiles, both determined from our longstanding Arecibo dual-frequency pulsar polarimetry programs. Many of the RM measurements were carried out toward the inner Galaxy and the Anticenter on pulsars with no previous determination, while others are re-measurements intended to confirm or improve the accuracy of existing values. Stokes-parameter profiles are displayed for the 58 pulsars for which no meaningful Stokes profile at lower frequency is available and four without a high frequency pair. This is a population that includes many distant pulsars in the inner Galaxy. A number of these polarized pulse profiles exhibit clear interstellar-scattering tails; nonetheless, we have attempted to interpret the associated emission-beam structures and to provide morphological classifications and geometrical models where possible.
