Parkes observations for project P1050 semester 2021OCTS_15

This is a request for observing time for the timing campaign of new pulsar discoveries from the reprocessing of the low-latitude Galactic plane section of the HTRU survey (P630). We have now completed 90 % of the survey with GPU based coherent acceleration search, template bank and fast folding algorithm pipelines, and now have discovered 92 previously unknown pulsars and 8 "class A" pulsars awaiting confirmation. \r\nInteresting science can usually only be derived from a new pulsar after confirmation and a follow-up timing campaign is carried out. One year of initial timing is the minimum timespan required to fully characterise any newly-discovered pulsars, essential for deriving pulsar parameters such as the characteristic age, magnetic field strength, spin-down rate, as well as to detect any unexpected behaviour of the pulsar which might result from emission instabilities. Pulsars on the observing list here have been confirmed in the previous and current 2021APRS semesters, the follow-up timing in OCTS2021 will produce completely new and exciting results. In addition, this timing project will allow us to measure the true Galactic plane pulsar population and the boundaries of pulsar parameter space in the galactic plane.

本申请旨在为HTRU巡天（HTRU survey）低纬度银道面（Galactic plane）区域再处理中新发现脉冲星（pulsar）的计时观测活动申请观测时间（项目编号P630）。目前，我们已通过基于GPU的相干加速搜索、模板库（template bank）和快速折叠算法（fast folding algorithm）流水线完成了90%的巡天工作，发现了92颗此前未知的脉冲星以及8颗待确认的“A类”脉冲星。
通常，只有在新脉冲星得到确认并开展后续计时观测活动后，才能从中获取有价值的科学成果。对任何新发现的脉冲星进行全面表征至少需要一年的初始计时观测，这对于推导脉冲星参数，例如特征年龄（characteristic age）、磁场强度（magnetic field strength）、自转角减速率（spin-down rate），以及检测可能由辐射不稳定性引起的脉冲星异常行为至关重要。观测列表中的脉冲星已在之前和当前的2021APRS学期得到确认，2021年10月学期（OCTS2021）的后续计时观测将产生全新且令人兴奋的结果。此外，该计时项目将使我们能够测量银道面脉冲星的真实种群数量以及银道面内脉冲星参数空间的边界。
