Parkes observations for project P1050 semester 2020APRS_25

This is a request for observing time for the initial follow-up of pulsar discoveries from the re-processing of the low-latitude Galactic plane section of the HTRU survey (P630). We have now completed a first pass re-processing of the 60 % of the survey with GPU based coherent acceleration search and template bank search pipelines, and have discovered potential 54 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 follow-up and 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.

本申请旨在为HTRU巡天（P630）低纬度银道面区域再处理所发现脉冲星的初始后续观测申请观测时间。我们已通过基于GPU的相干加速搜索与模板库搜索流水线，完成了该巡天60%数据的首轮再处理，并发现了54颗潜在的未知脉冲星。
通常，只有在对新发现脉冲星进行确认并开展后续计时观测计划后，才能从中获取有价值的科学成果。对新发现脉冲星进行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——这对于推导脉冲星的特征年龄、磁场强度、自旋减慢率等参数至关重要，同时也能探测因辐射不稳定性可能导致的任何意外行为。本后续与计时项目对于跟进HTRU银道面巡天中发现的所有潜在重要脉冲星系统而言是必要的。
由于观测清单中的所有脉冲星均为首次跟进，因此有望产生全新且令人振奋的研究成果。此外，本计时项目将助力对银道面脉冲星群体的大规模研究，探索脉冲星参数空间的真实边界。
