Precision orbital dynamics from interstellar scintillation arcs for PSR J0437-4715

Daniel J. Reardon, William A. Coles, Matthew Bailes +17

Intensity scintillations of radio pulsars are known to originate from interference between waves scattered by the electron density irregularities of interstellar plasma, often lead…

Comparison of Pulsar Positions from Timing and Very Long Baseline Astrometry

J. B. Wang, W. A. Coles, G. Hobbs +22

Pulsar positions can be measured with high precision using both pulsar timing methods and very-long-baseline interferometry (VLBI). Pulsar timing positions are referenced to a sola…
