Parkes observations for project P1054 semester 2023OCTS_01

With this proposal we ask time to continue our timing follow-up campaign of pulsars discovered with the MeerKAT telescope. Twentyfive sources have been discovered in targeted observations of Fermi unidentified point sources, one in association with a Supernova Remnant, 13 in the Magellanic Clouds, 72 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.

本提案旨在申请时间，以延续我们对MeerKAT望远镜发现的脉冲星开展的计时后续观测计划。其中25个源是在对费米（Fermi）未识别点源的靶向观测中发现的，1个与超新星遗迹（Supernova Remnant）相关联，13个位于麦哲伦云（Magellanic Clouds），72个位于球状星团（Globular Clusters），另有78个来自银道面巡天。新发现的脉冲星中，很大一部分是再生脉冲星（recycled pulsars），包括至少一个双中子星系统和若干'蜘蛛'双星（'spider' binaries），其余则为年轻脉冲星。计时观测对于充分挖掘脉冲星发现的全部潜力至关重要，它能够实现对旋转、天体测量及轨道参数的精确测量；而这些参数反过来又为我们提供了强有力的工具，助力深化对极端环境物理过程以及中子星整体种群的理解。Parkes望远镜的UWL接收器是一款高灵敏度、多功能的仪器，可成功对TRAPUM项目发现中亮度较高的这批新源进行计时观测。
