Coherent Emission from QED Cascades in Pulsar Polar Caps
Coherent Emission from QED Cascades in Pulsar Polar Caps
Pulsar magnetospheres are thought to be filled with electron-positron plasma generated in pair cascades. The driving mechanism of these cascades is the emission of gamma-ray photons and their conversion into pairs via Quantum Electrodynamics (QED) processes. In this work, we present 2D particle-in-cell simulations of pair cascades in pulsar polar …
