Induced Compton scattering in magnetized electron and positron pair plasma

Rei Nishiura, Shoma F. Kamijima, Masanori Iwamoto +1

A formulation for the parametric instability of electromagnetic (EM) waves in magnetized pair plasma is developed. The linear growth rate of induced Compton scattering is derived a…

Escape of cosmic rays from perpendicular shocks in the circumstellar magnetic field

Shoma F. Kamijima, Yutaka Ohira

We investigate the escape process of cosmic rays (CRs) from perpendicular shock regions of a spherical shock propagating to a circumstellar medium with the Parker-spiral magnetic f…
