Mapping Pulsar Emission Regions Using Interstellar Scintillation

Locating the pulsar radio emission region is a necessary component to understand the pulsar emission mechanism and coherent emission processes in general. Studies of pulsar emission regions are difficult, as they are very small and cannot be resolved using any conventional techniques. However, multi-path scattering in the interstellar medium provides effective interferometric baselines of sufficient length to probe deep within the pulsar magnetosphere and map this region. We have recently used interstellar scintillation to map the emission regions of pulsar B0834+06. To continue this program, we ask for 12 hours of observation time to follow up our previous targets and locate and map the emission regions of four additional pulsars amenable to this study.
