Parkes observations for project P1054 semester 2024APRS_10

With this proposal we ask time to continue our timing follow-up campaign of pulsars discovered with the MeerKAT telescope. Thirty sources have been discovered in targeted observations of Fermi unidentified point sources, two in association with a Supernova Remnant, 13 in the Magellanic Clouds, 87 in Globular Clusters and 78 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，以延续我们针对MeerKAT望远镜发现的脉冲星所开展的计时后续观测项目。本次发现的脉冲星分布如下：30颗来自费米未证认点源的靶向观测，2颗与超新星遗迹（Supernova Remnant）成协，13颗位于麦哲伦云，87颗位于球状星团（Globular Clusters），另有78颗来自银道面巡天。这批新发现的脉冲星中，相当一部分属于再循环脉冲星（包括至少1个双中子星系统与多组‘蜘蛛’双星），亦或是年轻脉冲星。计时观测对于充分挖掘每一颗脉冲星发现的科学潜力具有核心作用：通过计时观测可精确测量其自转、天体测量与轨道参数，进而为我们深化对极端环境物理规律以及整体中子星族群的认知提供强有力的工具。帕克斯望远镜（Parkes Telescope）搭载的UWL接收机（UWL receiver）是一台高灵敏度、多用途的观测设备，可助力我们成功对这批新发现源开展计时观测——这批源均属于TRAPUM巡天中亮端的发现样本。
