John Kirk's Astrophysics Projects

  • Pulsar winds: how is the energy of the fly-wheel transferred to the surroundings?

  • Modelling blazars: how can one account for the extremely rapid, large amplitude fluctuations in the gamma-ray output of blazars? A new suggestion was presented at IAU 275, "Jets on all scales"

  • How do cosmics rays manage to amplify the magnetic field at a shock front? Here is a recent publication.

  • Particle acceleration: what are the signatures of stochastic acceleration at shock fronts? Relativistic shocks have been the subject a lot of analytic and numerical work. This summary describes the theoretical predictions, which are now being tested by simulations
