50 picoarcsec astrometry of pulsar emission

We use very long baseline interferometry (VLBI) imaging of the interstellar scattering speckle pattern associated with the pulsar PSR 0834+06 to measure the astrometric motion of its emission. The D ~ 5 au interstellar baselines, provided by interference between speckles spanning the scattering disc...
