Coherent curvature radiation

WebMay 3, 2024 · We consider a generic model of coherent curvature radiation by bunches of charged particles in a NS magnetosphere. The specific geometry does not matter, as long as the bunches are generated abruptly and stream outward along open magnetic field lines. The field lines sweep across the line of sight (LOS) as the magnetosphere rotates.

WebJan 24, 2024 · Within the framework of coherent curvature radiation by bunches, φ t or bunch geometry can significantly affect the emission polarization. As shown in Figure 2 , if φ t becomes larger or γ becomes smaller, the red solid and dotted–dashed lines will move in the direction of increasing φ . WebFeb 19, 2024 · Inside the magnetosphere, we investigate the polarization properties of both coherent curvature radiation and inverse Compton scattering by charged bunches. In order to have the majority of bursts not having high circular polarization, the bunches should have a large cross section involving a bunch of field lines.
