Parkes observations for project P1054 semester 2020APRS_12

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）巡天潜在新发现源的后续观测计划。该巡天计划预计于2020年1月启动。预计在巡天运行的首个半年内，通过对超新星遗迹、脉冲星风云以及费米（Fermi）未证认点源开展靶向指向观测，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颗新发现脉冲星的科研潜力至关重要：通过计时观测可精确测量其自转、天体测量与轨道参数，进而为我们深入理解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接收机是一台高灵敏度、多用途的观测设备，能够助力我们顺利完成TRAPUM巡天中亮端脉冲星的计时观测工作。
本次申请将为每一颗在1.4 GHz频段下流量密度高于约60微央斯基的TRAPUM新发现脉冲星，提供每月最长2小时的计时观测时长。
