Pulsed high energy gamma-rays from thermal populations in the current sheets of pulsar winds
Ioanna Arka, Guillaume Dubus
Context. More than one hundred GeV pulsars have been detected up to now by the LAT telescope on the Fermi gamma-ray observatory, showing peak energies around a few GeV. Current mod…
Linearly polarized superluminal waves in pulsar winds
Ioanna Arka, John G. Kirk
Pulsar winds are the ideal environment for the study of non-linear electromagnetic waves. It is generally thought that a pulsar launches a striped wind, a magnetohydrodynamic entro…
Of Winds and Waves
John G. Kirk, Ioanna Arka
Recent work on the properties of superluminal waves in pulsar winds is summarized. It is speculated that these waves play an important role in the termination shock that divides th…
Superluminal waves in pulsar winds
Ioanna Arka, John G. Kirk
The energy lost by a rotation-powered pulsar is carried by a relativistic flow containing a mixture of electromagnetic fields and particles. In the inner regions, this is thought t…
Pair production in counter-propagating laser beams
J. G. Kirk, A. R. Bell, I. Arka
Based on an analysis of a specific electron trajectory in counter-propagating beams, Bell & Kirk (PRL 101, 200403 (2008)) recently suggested that laboratory lasers may shortly be a…
