Parkes observations for project P860 semester 2019APRS_07

This is a request for observing time for the initial follow-up of pulsar discoveries from the low-latitude Galactic plane section of the HTRU survey (P630). We have now completed a first pass processing of the entire survey with our periodicity search algorithm as well as the partially-coherent segmented acceleration search pipeline, and have discovered 106 previously unknown pulsars. \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 ?eld strength, spin-down rate, as well as to detect any unexpected behaviour of the pulsar which might result from emission instabilities. \r\nThis follow-up timing project is necessary for following up on any interesting pulsar systems discovered from the HTRU Galactic plane survey. Since all of the pulsars on the observing list here are being followed-up for the first time, they will produce completely new and exciting results. In addition, this timing project will enable a large-scale examination of the Galactic plane pulsar population, exploring the true boundaries of pulsar parameter space.

本申请为HTRU巡天（P630）银道面低纬区域内新发现脉冲星（pulsar）的首次后续观测申请分配观测时长。目前，我们已利用周期搜索算法与部分相干分段加速搜索流水线（partially-coherent segmented acceleration search pipeline）完成了整个巡天的首轮数据处理，共发现106颗此前未被发现的脉冲星。
通常而言，新发现脉冲星仅在完成确认并开展后续计时观测项目后，方能产出有价值的科学成果。对所有新发现脉冲星开展为期一年的初始计时观测，是完成其完整特性表征的最低时长要求——这一过程对于获取脉冲星的特征年龄、磁场强度、自转减慢速率等参数，以及探测可能由辐射不稳定性引发的脉冲星异常行为均至关重要。
本后续计时观测项目可对HTRU银道面巡天中发现的所有具科学价值的脉冲星系统开展跟进研究。由于本次观测列表中的所有脉冲星均为首次接受后续观测，其相关研究将产出全新且极具意义的成果。此外，本计时观测项目可实现对银道面脉冲星种群的大规模普查，进而探索脉冲星参数空间的真实边界。
