The High Time Resolution Universe Pulsar Survey - VI. An artificial neural network and timing of 75 pulsars

摘要: We present 75 pulsars discovered in the mid-latitude portion of High Time Resolution Universe survey, 54 which have full timing solutions. All spin periods greater than 100 ms, and none those with solutions is binaries. Two display particularly interesting behaviour; PSR J1054−5944 found to be an intermittent pulsar, J1809−0119 has glitched twice since its discovery. In second half paper we discuss development application artificial neural network data-processing pipeline for survey. tests that were used generate scores find our was able reject over 99 per cent candidates produced data processing, blindly detect 85 pulsars. suggest improvements accuracy should possible if further care taken when training network; example, ensuring a representative sample pulsar population during process, or use different networks detection types
