Observational Constraints on Pulsar Wind Theories
J. G. Kirk
Two-dimensional, relativistic, MHD simulations of pulsar-wind powered nebulae provide strong constraints on the properties of the winds themselves. In particular, they confirm that…
Particle Acceleration in Relativistic Flows
J. G. Kirk
A property common to several different astrophysical sources of high-energy gamma-rays is the presence of bulk motion at relativistic speed. The intrinsic spectra of the nonthermal…
The "sigma" problem of the Crab pulsar wind
J. G. Kirk, O. Skjaeraasen
The conversion of the Crab pulsar wind from one dominated by Poynting flux close to the star to one dominated by particle-born energy at the termination shock is considered. The id…
A wind model for high energy pulses
J. G. Kirk, O. Skjaeraasen, Y. A. Gallant
A solution to the sigma problem - that of finding a mechanism capable of converting Poynting energy flux to particle-borne energy flux in a pulsar wind - was proposed several years…
Modelling Plerion Spectra and their Evolution
Yves A. Gallant, Eric van der Swaluw, John G. Kirk +1
We review recent theoretical developments on pulsar winds, their nebulae and relativistic shock acceleration, and show how they illuminate unsolved problems in plerion spectra, in…
Size-Luminosity scaling and Inverse Compton Seed Photons in Blazars
Markos Georganopoulos, John G. Kirk, Apostolos Mastichiadis
We present preliminary results of our work on blazar unification. We assume that all blazars have a broad line region (BLR) and that the size of the BLR scales with the power of th…
