Parkes observations for project P860 semester 2018APRS_05

This is a request for observing time for the initial follow-up of pulsar discoveries from the low-latitude Galactic plane section of the HTRU survey (P630). We have already discovered 105 pulsars from 94% of processed data. We expect that processing should be complete within the 2018APRS semester. Extrapolation and population synthesis shows that the Galactic plane survey should result in a further 5-10 discoveries.\r\n\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 ?eld strength, spin-down rate, as well as to detect any unexpected behaviour of the pulsar which might result from emission instabilities.\r\n\r\nThis follow-up timing project is necessary for identifying 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. Given the large number of discoveries expected and the long integration length required, this dedicated follow-up timing campaign is vital for achieving our science goals.

本申请旨在为HTRU巡天（HTRU Survey）P630项目银道面低纬度区域发现的脉冲星（pulsar）申请首次后续观测所需的观测时长。目前我们已完成94%的已处理数据，从中发现了105颗脉冲星。预计全部数据处理工作将于2018年APRS观测周期内完成。通过外推分析与种群合成研究可知，本次银道面巡天预计还将新增5至10颗脉冲星发现。

新发现的脉冲星通常仅在完成证认并开展后续计时观测项目后，才能产出具有科学价值的研究成果。为完整表征每一颗新发现脉冲星的物理特性，至少需要开展为期一年的初始计时观测，这对于获取脉冲星的特征年龄、磁场强度、自旋减速率等关键参数，以及探测由辐射不稳定性引发的脉冲星异常行为而言必不可少。

本次后续计时观测项目对于甄别HTRU银道面巡天中发现的各类具有科学价值的脉冲星系统至关重要。由于本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性与突破性。此外，本计时项目将实现对银道面脉冲星种群的大规模普查，探明脉冲星参数空间的真实边界。鉴于预期发现的脉冲星数量较多且所需积分时长较长，本次专属后续计时观测项目对于达成我们的科学目标而言不可或缺。
