Parkes observations for project P1050 semester 2020OCTS_10

This is a request for observing time for the timing campaign of new pulsar discoveries and follow-up of expected new potential pulsars from the re-processing of the low-latitude Galactic plane section of the HTRU survey (P630). We have now completed the first pass re-processing of the 62 % of the survey with GPU based coherent acceleration search and template bank search pipelines, and have discovered 51 previously unknown pulsars. Interesting 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. This 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 have been confirmed in the current 2020APRS semester, the follow-up timing 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 in the galactic plane.

这是一份观测时间申请，旨在为新发现脉冲星开展计时观测 campaign，并对HTRU巡天（P630）低纬度银道面区域重新处理后预期出现的潜在新脉冲星进行后续观测。目前，我们已完成该巡天62%区域的首轮重新处理——通过基于GPU的相干加速搜索与模板库搜索流水线实现——并发现了51颗此前未知的脉冲星。通常，只有在确认新脉冲星并开展后续计时观测 campaign后，才能从中挖掘出有价值的科学成果。对任何新发现的脉冲星而言，为期一年的初始计时观测是全面表征其特性的最短时间跨度，这对于推导脉冲星参数（如特征年龄、磁场强度、自旋减慢率）以及探测可能由辐射不稳定性导致的意外行为至关重要。本计时项目对于后续研究HTRU银道面巡天中发现的有趣脉冲星系统不可或缺。由于观测清单中的所有脉冲星均已在当前2020APRS学期得到确认，后续计时观测将产生全新且令人振奋的结果。此外，本项目将推动对银道面脉冲星群体的大规模研究，探索银道面脉冲星参数空间的真实边界。
