Parkes observations for project P1067 semester 2020APRS_21

The Parkes Ultra-wide-bandwidth receiver enables, for the first time with the Parkes telescope, a commensal high time and high frequency resolution survey. We will observe Baade's window in which we are guaranteed detections of pulsars and spectral lines. Our science drivers are diverse and range from understanding scattering, to detecting new pulsars, to searching for galaxies in the zone of avoidance, probing the globular cluster at the centre of the window and studying OH circumstellar masers and CO-dark molecular gas. The observing strategy and processing software developed for this survey will be applicable to all future Parkes surveys with the wide-band receiver or cyrogenically-cooled phased array feed.

帕克斯超宽带接收机（Parkes Ultra-wide-bandwidth receiver）首次在帕克斯望远镜上实现了共生式高时间分辨率与高频率分辨率巡天观测。我们将对巴德窗（Baade's window）开展观测，该天区可确保我们探测到脉冲星与谱线。本项目的科学研究目标多元，涵盖星际散射机制研究、新脉冲星搜寻、银道面消隐带内星系探测、巴德窗中心球状星团的探测分析，以及羟基星周脉泽（OH circumstellar masers）与CO暗分子气体（CO-dark molecular gas）的相关研究。为本次巡天开发的观测策略与数据处理软件，可推广应用于未来所有搭载超宽带接收机或低温冷却相控阵馈源（cyrogenically-cooled phased array feed）的帕克斯望远镜巡天项目。
