Rejuvenating the shells of supernova remnants by pulsar winds
Eric van der Swaluw, Abraham Achterberg, Yves A. Gallant
We reconsider the rejuvenation mechanism as proposed by Shull, Fesen, & Saken (1989). These authors suggest that an active pulsar can catch up with, and rejuvenate the shell of the…
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…
Pulsar wind nebulae in supernova remnants
E. van der Swaluw, A. Achterberg, Y. A. Gallant +1
A spherically symmetric model is presented for the interaction of a pulsar wind with the associated supernova remnant. This results in a pulsar wind nebula whose evolution is coupl…
Intergalactic Propagation of UHE Cosmic Rays
Abraham Achterberg, Yves A. Gallant, Colin A. Norman +1
We discuss the intergalactic propagation of ultra-high-energy cosmic rays (UHECRs) with energies E \geq 10^{18.5} eV. We consider the propagation of UHECRs under the influence of t…
