Parkes observations for project P1050 semester 2020OCTS_03

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.\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. 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.

本申请为观测时间申请，用于开展新脉冲星（pulsar）发现的计时观测项目，以及对HTRU巡天（HTRU Survey）低银道面区域再处理流程中预期发现的潜在新脉冲星进行后续跟进观测，该巡天项目编号为P630。
目前，我们已基于图形处理器（GPU）的相干加速搜索（coherent acceleration search）与模板库搜索（template bank search）流程，完成了该巡天62%区域的首轮再处理，并发现了51颗此前未被记录的脉冲星。
通常而言，新发现的脉冲星仅在得到确认并开展后续计时观测项目后，才能产出有价值的科学成果。
对新发现的脉冲星开展至少一年的初始计时观测，是完整表征其物理特性的最低时长要求，这对于获取脉冲星的特征年龄、磁场强度、自转减慢率（spin-down rate）等参数，以及探测可能由射电辐射不稳定性引发的脉冲星异常行为均至关重要。
本计时观测项目对于跟进HTRU银道面巡天中发现的各类有科学价值的脉冲星系统而言是必要的。
由于本次观测清单中的所有脉冲星均已在2020APRS观测学期中得到确认，本次后续计时观测将产出全新且极具科学价值的成果。
此外，本计时观测项目将支持对银道面脉冲星族群开展大规模普查，进而探索银道面内脉冲星参数空间的真实边界。
