Parkes observations for project P1067 semester 2020APRS_12

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首次让帕克斯望远镜实现了兼具高时间分辨率与高频谱分辨率的共生巡天。我们将观测巴德窗（Baade's Window），该区域可确保探测到脉冲星与谱线。我们的科学目标广泛多样，涵盖散射现象的理解、新脉冲星的探测、隐带（Zone of Avoidance）中星系的搜寻、窗中心球状星团的探测，以及羟基星周脉泽（OH circumstellar masers）与CO暗分子气体（CO-dark molecular gas）的研究。为本巡天开发的观测策略与处理软件，将适用于未来帕克斯望远镜使用宽带接收机或低温冷却相控阵馈源（cryogenically-cooled phased array feed）开展的所有巡天项目。
