Parkes observations for project P1178 semester 2024APRS_02

We are actively developing a new version of the ATNF pulsar catalogue. In the paper describing the new catalogue we wish to take the opportunity to publish important pulsar parameters that have, to-date, not been published. The fundamental property of a pulsar is its pulse period and yet we have identified a large number of pulsars that do not having a measured spin-down rate and hence we do not know their evolutionary state, nor have good positions or knowledge of whether they are in a binary system. We have therefore selected 53 pulsars with the goal of measuring their spin-down rates. During this project we will also develop an automated pulsar-fold-mode online processing pipeline that includes online RFI mitigation. This pipeline will be made available as an ATNF service for other users.

我们正积极推进澳大利亚望远镜国家设施（Australia Telescope National Facility, ATNF）脉冲星目录的新版本开发工作。在阐述该新版目录的研究论文中，我们希望借此契机发布一批迄今为止尚未公开的重要脉冲星参数。脉冲星的核心属性为其脉冲周期，但我们已发现大量脉冲星尚未测得其自转减慢速率（spin-down rate），因此既无法知晓它们的演化状态，也无法获取精确的位置信息，更无法确认其是否处于双星系统中。为此我们遴选了53颗脉冲星，旨在测定它们的自转减慢速率。在本项目实施期间，我们还将开发一套集成在线射频干扰（Radio Frequency Interference, RFI）抑制功能的自动化脉冲星折叠模式在线处理流水线（pipeline）。该处理流水线将作为ATNF的一项服务面向其他用户开放。
