A joint radio gamma-ray variability study of the crab pulsar

| description | In order to understand pulsar emission, and coherent emission processes in general, it is important to assess the relationship between high energy and radio emission. Gamma-ray radio correlations can be used to test whether observed radio variability is solely the result of modifications to the radio emission processes (e.g., non-linear wave propagation [1]) or associated with bulk changes in the pulsar magnetosphere and charged particle flow (e.g., [2] and [3]). In the former case, gamma-ray emission would not be correlated with radio variability, but in the latter case, a pronounced correlation between gamma-rays would be expected. Giant radio pulses from the Crab pulsar [4] provide the best opportunity to study this relationship because they occur relatively frequently and provide a non-stationary signal which can be correlated against the high energy emission. |
