Parkes observations for project P1054 semester 2024OCTS_02

With this proposal we ask time to continue our timing follow-up campaign of pulsars discovered with the MeerKAT telescope. Thirtysix sources have been discovered in targeted observations of Fermi unidentified point sources, two in association with a Supernova Remnant, 14 in the Magellanic Clouds, 94 in Globular Clusters and 81 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.

本提案申请观测时长，以延续对米尔卡特（MeerKAT）望远镜发现的脉冲星开展的计时随访项目。本次新发现的脉冲星中，通过对费米（Fermi）未证认点源的靶向观测发现36颗，与超新星遗迹成协发现2颗，在麦哲伦星云（Magellanic Clouds）中发现14颗，在球状星团（Globular Clusters）中发现94颗，在银道面巡天中发现81颗。其中多数为再循环脉冲星（包括至少1个双中子星系统与多组‘蜘蛛’双星系统），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研价值至关重要，其可精准测量脉冲星的自转、天体测量与轨道参数，进而为我们深入理解极端环境下的物理规律以及整体中子星族群特性提供强有力的研究工具。帕克斯（Parkes）望远镜的UWL接收机是一台高灵敏度、多功能的观测设备，能够助力我们对这批TRAPUM巡天亮端新发现的脉冲星源开展成功计时观测。
