Parkes observations for project P1067 semester 2020APRS_18

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）首次借助帕克斯望远镜（Parkes telescope）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（pulsars）与谱线（spectral lines）。我们的科学研究目标多元且广泛，涵盖散射现象的机制解析、新脉冲星的探测、银河回避区（zone of avoidance）内星系的搜寻、巴德窗中心球状星团的探测研究，以及对羟基（OH）星周脉泽（circumstellar masers）与CO暗分子气体（CO-dark molecular gas）的观测分析。为本巡天开发的观测策略与处理软件，可适用于未来所有搭载宽带接收机或低温冷却相控阵馈源（cyrogenically-cooled phased array feed）的帕克斯巡天项目。
