Scientific paper

In January of this year, the Vela pulsar underwent the largest spin-rate change in the thirty years since timing observations began. We observed the source twice, ~3.5 and ~35 days after the event, revealing a remarkable nebular structure surrounding the pulsar, setting strong constraints on pulse profile changes following the glitch, and finding significant changes in the nebular emission at roughly the light-travel time from the pulsar a month following the event. We propose here to obtain a third epoch of pulsar and nebula observations in order to constrain glitch models by assessing the pulse-shape stability and exploring further the changes in the nebular structure. As with our TOO observations, we will waive proprietary rights to these data.
