The Fast Radio Burst Luminosity Function and Death Line in the Low-Twist Magnetar Model
Zorawar Wadiasingh, Paz Beniamini, Andrey Timokhin +4
We explore the burst energy distribution of fast radio bursts (FRBs) in the low-twist magnetar model of Wadiasingh and Timokhin (2019). Motivated by the power-law fluence distribut…
Origin of Pulsar Radio Emission
Alexander Philippov, Andrey Timokhin, Anatoly Spitkovsky
Since pulsars were discovered as emitters of bright coherent radio emission more than half a century ago, the cause of the emission has remained a mystery. In this Letter we demons…
High resolution numerical modeling of the force-free pulsar magnetosphere
Andrey Timokhin
We consider the force-free magnetosphere of an aligned rotator. Its structure is well described by a Grad-Shafranov equation for poloidal magnetic field, the so-called "pulsar equa…
3D Kinetic Pulsar Magnetosphere Models: Connecting to Gamma-Ray Observations
Constantinos Kalapotharakos, Gabriele Brambilla, Andrey Timokhin +2
We present 3D global kinetic pulsar magnetosphere models, where the charged particle trajectories and the corresponding electromagnetic fields are treated self-consistently. For ou…
Coherence of Multi-Dimensional Pair Production Discharges in Polar Caps of Pulsars
Alexander Chernoglazov, Alexander Philippov, Andrey Timokhin
We report on the first self-consistent multidimensional particle-in-cell numerical simulations of non-homogeneous pair discharges in polar caps of rotation-powered pulsars. By intr…
Electron positron pair flow and current composition in the pulsar magnetosphere
Gabriele Brambilla, Constantinos Kalapotharakos, Andrey Timokhin +2
We performed ab-initio Particle-In-Cell (PIC) simulations of a pulsar magnetosphere with electron-positron plasma produced only in the regions close to the neutron star surface. We…
