Parkes observations for project P1054 semester 2024APRS_12

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.

本申请旨在延续我们对使用MeerKAT望远镜发现的脉冲星开展的计时观测随访项目，并申请相应观测机时。本次新发现的脉冲星分布如下：在费米（Fermi）未证认点源的靶向观测中发现30颗，与超新星遗迹（Supernova Remnant）成协的有2颗，麦哲伦云（Magellanic Clouds）中发现13颗，球状星团（Globular Clusters）中发现87颗，银道面巡天中发现78颗。本次新发现的脉冲星中，绝大多数为再循环脉冲星（recycled pulsars），包含至少1个双中子星系统与数例‘蜘蛛’双星系统，另有部分为年轻脉冲星。计时观测对于充分挖掘每一颗脉冲星发现的科研潜力至关重要：通过计时观测可精确测定其自转、天体测量与轨道参数，进而为我们研究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）望远镜搭载的UWL接收机（UWL receiver）是一款高灵敏度、多用途的观测设备，可助力我们成功对这批TRAPUM巡天亮端的新发现脉冲星开展计时观测。
