Spectral and Polarization Properties of Coherent Radio Emission from Relativistic Magnetized Pair Plasma Shocks
Yuanhong Qu, Joonas Nättilä, Lorenzo Sironi
Fast radio bursts (FRBs) are millisecond-duration radio transients whose emission mechanism remains an open question. The so-called synchrotron maser instability in relativistic ma…
Monte Carlo sampling of first-order QED processes in laser and pulsar plasmas
Verneri Sarjomaa, Joonas Nättilä
Monte Carlo sampling of strong-field quantum electrodynamics processes underpins simulations of high-intensity laser experiments and of astrophysical compact-object magnetospheres.…
Pair Discharges and Radio Emission from Millisecond-Pulsar and White-Dwarf Magnetospheres
Tuomo Salmi, Joonas Nättilä
Coherent radio emission is observed from compact astrophysical objects with relatively weak magnetic fields, including millisecond pulsars and white dwarfs, the latter being propos…
Pair Discharges and Radio Emission from Pulsar Magnetospheres
Joonas Nättilä, Tuomo Salmi
Radio pulsars can power their coherent radio emission through intermittent plasma discharges in magnetospheric gaps. The nonlinear coupling between particle acceleration, quantum e…
