Parkes observations for project P1054 semester 2023APRS_13

With this proposal we ask time to continue our timing follow-up campaign of pulsars discovered with the MeerKAT telescope. Twenty sources have been discovered in targeted observations of Fermi unidentified point sources, one in association with a Supernova Remnant, 13 in the Magellanic Clouds, 71 in Globular Clusters and 74 in a survey of the Galactic plane. A large fraction of the new discoveries are recycled pulsars (including at least one double neutron star system and several 'spider' binaries), or young pulsars. Timing observations have an essential role in exploiting the full potential of any pulsar discovery, allowing the precise measurement of rotational, astrometric and orbital parameters which, in turn, give us powerful tools to improve our understanding of the physics in extreme environments as well as of the population of neutron stars as a whole. The UWL receiver of the Parkes telescope is a sensitive, versatile instrument that is allowing us to successfully time these new sources, in the bright-end of TRAPUM discoveries.

本申请旨在延续我们对MeerKAT望远镜（MeerKAT telescope）所发现脉冲星的计时后续观测项目。本次发现的脉冲星来源涵盖：在费米未证认点源（Fermi unidentified point sources）靶向观测中发现20颗，与超新星遗迹（Supernova Remnant）成协1颗，麦哲伦云（Magellanic Clouds）中发现13颗，球状星团（Globular Clusters）中发现71颗，银河平面巡天（Galactic plane survey）中发现74颗。
本次新发现的脉冲星中，很大一部分为再循环脉冲星，包括至少1个双中子星系统与多颗“蜘蛛”双星系统脉冲星，或是年轻脉冲星。
计时观测对于充分发挥每一颗脉冲星发现的科学潜力至关重要，其可实现自转参数、天体测量参数与轨道参数的精准测定，进而为我们深入理解极端环境下的物理规律，乃至整体中子星的种群分布提供强有力的研究工具。
帕克斯望远镜（Parkes telescope）的UWL接收机是一款高灵敏度、多用途的观测仪器，可助力我们对TRAPUM巡天亮端的这批新发现源开展成功的计时观测。
