Parkes observations for project P1067 semester 2020APRS_17

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（Parkes telescope）上实现了共生式高时间分辨率与高频率分辨率巡天观测。本项目将对巴德窗（Baade's window）开展观测，该区域可确保探测到脉冲星与谱线。我们的科学研究目标涵盖广泛：从阐释散射机制、探测新脉冲星，到在回避区（zone of avoidance）中搜寻星系，探测巴德窗中心的球状星团，以及研究羟基星周脉泽（OH circumstellar masers）与CO暗分子气体（CO-dark molecular gas）。本次巡天所开发的观测策略与处理软件，可适配未来所有搭载超宽带接收机或低温冷却相控阵馈源的帕克斯望远镜巡天项目。
