Parkes observations for project P1054 semester 2024APRS_08

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.

本观测提案旨在申请观测时长，以延续基于米尔卡特（MeerKAT）望远镜发现的脉冲星的计时后续观测计划。本次研究中，我们通过靶向观测费米（Fermi）未证认点源发现了30颗脉冲星；另有2颗与超新星遗迹（Supernova Remnant）成协，13颗位于麦哲伦云，87颗发现于球状星团（Globular Clusters），78颗来自银道面巡天。其中多数新发现脉冲星为再循环脉冲星（recycled pulsars），包括至少1个双中子星系统与多颗‘蜘蛛型’双星，亦有部分为年轻脉冲星。
计时观测对于充分挖掘脉冲星发现的全部科学潜力至关重要：通过计时观测可精确测量其自转、天体测量与轨道参数，进而为我们理解极端环境下的物理规律以及整体中子星族群提供强有力的研究工具。帕克斯（Parkes）望远镜的UWL接收机（UWL receiver）是一款高灵敏度、多用途的观测设备，能够助力我们顺利完成这批TRAPUM巡天亮源样本的计时观测工作。
