Parkes observations for project P1054 semester 2020APRS_10

With this proposal we ask time to begin a follow-up campaign of potential new discoveries from the TRAPUM (TRAnsients and PUlsars with Meerkat) survey, which is due to start in January 2020. About 10 new pulsars are expected to be found during the first semester of operations, in targeted pointings towards supernova remnants, pulsar wind nebulae and Fermi unidentified point sources. 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 will allow us to successfully time the bright-end of TRAPUM discoveries. We here request (up to) 2-hr long monthly observations of any new TRAPUM pulsar with a flux density at 1.4 GHz above $\\sim 60 \\mu$Jy.

本提案申请观测时长，以启动针对TRAPUM（TRAnsients and PUlsars with Meerkat，即Meerkat望远镜瞬变源与脉冲星巡天）巡天项目潜在新发现天体的后续观测计划，该巡天原定于2020年1月启动。在该巡天运行的首学期内，针对超新星遗迹、脉冲星风云及费米未证认点源开展的靶向观测中，预计将发现约10颗新脉冲星。脉冲星计时观测对于充分挖掘每一次脉冲星发现的科研潜力具有核心作用：通过计时观测可精确测定脉冲星的自转、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，可助力我们对TRAPUM巡天发现的亮端脉冲星开展有效计时观测。本次申请计划每月对所有在1.4 GHz频段下流量密度高于约60微央斯基（μJy）的TRAPUM新发现脉冲星开展时长可达2小时的观测。
