Parkes observations for project P1050 semester 2020APRS_04

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（High Time Resolution Universe Survey）低银纬银道面片区重新处理流程中发现的脉冲星，申请开展初步后续观测所需的观测时长（项目编号P630）。
目前，我们已利用基于图形处理器（Graphic Processing Unit，GPU）的相干加速搜索与模板库搜索流程，完成了该巡天60%片区的首轮重新处理，并发现了54颗潜在的此前未被发现的脉冲星。
通常而言，仅在完成脉冲星确认并开展后续计时观测项目后，才能从新发现的脉冲星中获取有价值的科学成果。
对新发现的脉冲星开展为期一年的初步计时观测，是完整表征其物理特性的最低时长要求，这对推导脉冲星的特征年龄、磁场强度、自转减速率等参数，以及探测由辐射不稳定性引发的脉冲星异常行为至关重要。
本后续观测与计时项目，是对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跟进研究的必要环节。
由于本次观测列表中的所有脉冲星均为首次开展后续观测，其研究成果将具备全新的科学价值与突破性意义。
此外，本计时项目将支持对银道面脉冲星族群开展大规模普查，全面探索脉冲星参数空间的真实边界。
