Pulse Profiles and Polarization Characteristics of Non-Thermal Emission from Pulsar Magnetospheres

Shota Kisaka

In pulsar magnetosphere, particles are accelerated and emit high-energy photons. Possible origins of non-thermal pulsed emissions have been discussed at the inner region (polar cap), and outer region of the magnetosphere (outer gap). Recent particle simulations have shown that the particle acceleration could occur at the current sheet outside the light cylinder. Pulsed emission is an important tool for probing the particle acceleration and creation. We discuss the expected pulse profiles and polarization characteristics of pulsed emissions to test the acceleration models by future observations.
