A coherent acceleration search of the Parkes multi-beam pulsar survey - techniques and the discovery and timing of 16 pulsars

Abstract

A fully coherent acceleration search algorithm has been applied to the Parkes multi- beam pulsar survey of the Galactic plane to search for previously undiscovered relativistic binary pulsars. The search has resulted in the discovery of 16 pulsars including a binary millisecond pulsar and an intermittent pulsar. Despite a number of promising candidates there have been no new discoveries of relativistic binary pulsars. Here we detail the acceleration search performed in our analysis and present coherent timing solutions for each of pulsars discovered. In light of the lack of discoveries of relativistic binary pulsars, we also discuss the technique of acceleration searching and its effectiveness in finding these systems.
