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）首次借助帕克斯望远镜（Parkes telescope）实现了兼具高时间分辨率与高频率分辨率的共生观测巡天。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（pulsars）与天体谱线（spectral lines）。本次巡天的科学目标多元丰富，涵盖探究射电散射机制、探测新脉冲星、搜寻隐带（zone of avoidance）内的河外星系、探查巴德窗中心的球状星团（globular cluster），以及研究OH星周脉泽（OH circumstellar masers）与CO暗分子气体（CO-dark molecular gas）。为本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宽带接收机（wide-band receiver）或低温冷却相控阵馈源（cryogenically-cooled phased array feed）的帕克斯望远镜观测巡天。
