Pulsar variability, the radio emission mechanism and pulsar timing

  • Are average radio pulse profiles generally intrinsically variable?
  • How do single pulse phenomena relate to average profile variability?
  • What does long term variability tell us about the radio emission mechanism?
  • How are magnetospheric processes related to pulsar radio emission affecting pulsar rotation?
  • What is the role of interstellar propagation effects?

We are pursuing the above questions, using novel techniques and high quality data from the world's most sensitive telescopes.
