Parkes observations for project P1054 semester 2023OCTS_12
收藏资源简介:
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.
本提案申请观测时长,以延续针对米尔卡特望远镜(MeerKAT telescope)所发现脉冲星的计时后续观测项目。本次通过费米未证认点源(Fermi unidentified point sources)靶向观测共发现25个脉冲星源,其中1个与超新星遗迹(Supernova Remnant)成协,13个位于麦哲伦星云(Magellanic Clouds),72个位于球状星团(Globular Clusters),另有78个来自银道面巡天。本次新发现的脉冲星中,很大一部分为再循环脉冲星(包括至少1个双中子星系统与多颗"蜘蛛"双星系统脉冲星),或是年轻脉冲星。计时观测对于充分挖掘每一次脉冲星发现的全部科研潜力具有核心作用:通过计时观测可精准测量其自转、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。帕克斯望远镜(Parkes telescope)的UWL接收机是一台高灵敏度、多用途的仪器,可帮助我们成功完成这批新发现源的计时观测——这批源均属于TRAPUM巡天中亮源端的发现成果。
