Parkes observations for project P1050 semester 2020APRS_24

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.本申请为HTRU巡天（HTRU Survey，项目编号P630）银道面低纬度区域重新处理工作所发现的脉冲星，申请开展初始后续观测所需的观测时长。目前，我们已依托基于图形处理器（GPU）的相干加速搜索与模板库搜索流程，完成该巡天60%区域的首轮重新处理，并发现54颗潜在的此前未被发现的脉冲星。通常而言，新发现的脉冲星仅在完成确认并开展后续计时观测项目后，方能产出具备科学价值的研究成果。初始计时观测需至少持续一年，这是完整表征所有新发现脉冲星的最短时长要求；而完整推导脉冲星的特征年龄、磁场强度、自转减慢率等参数，以及探测可能由辐射不稳定性引发的脉冲星异常行为，均需依托该观测时长。本后续观测与计时项目，是针对HTRU银道面巡天中发现的各类具有科学价值的脉冲星系统开展后续研究的必要环节。由于本次观测清单中的所有脉冲星均为首次开展后续观测，本项目将产出全新且极具突破性的研究成果。此外，本计时项目还将实现对银道面脉冲星族群的大规模普查，深入探索脉冲星参数空间的真实边界。
