Deep Analyses of Nulling in Arecibo Pulsars Reveal Further Periodic Behavior

Abstract

Sensitive Arecibo observations provide an unprecedented ability to detect nulls for an accurate pulse-modulation quelling (PMQ) analysis. We demonstrate that a number of conal pulsars show "periodic nulling" similar to the phenomenon found earlier in pulsar B1133+16.
