AN EMISSION MECHANISM EXPLAINING OFF-PULSE EMISSION ORIGINATING IN THE OUTER MAGNETOSPHERE OF PULSARS

We have examined the cyclotron resonance instability developing in the relativistic outflowing plasma in the pulsar magnetosphere. The instability condition leads to radio emission in the subgigahertz frequency regime which is likely to be seen as off-pulse emission. Recent studies have shown the presence of off-pulse emission in long period pulsars, and we demonstrate this plasma process to be an energetically viable mechanism.
