A next-generation receiver for Radio Astronomy

该项目将提供下一代射电天文接收器，用于帕克斯射电望远镜。这一设施将大大提高性能，特别是在灵敏度和调查速度方面。科学目标是通过对快速射电爆发和中性氢的观测，更好地了解宇宙网络中的电离和中性成分，以及它们的演化。利用这一设施还将在理解脉冲星、分子、射电星系和宇宙射线方面取得进展。该技术基于大型相控阵馈电的低温冷却。与Parkes和澳大利亚SKA探路者(ASKAP)望远镜上现有的接收器相比，这款接收器是一个重大进步。

This project will provide a next-generation radio astronomy receiver to be used on the Parkes radio telescope. This facility will provide a major increase in performance, particularly in sensitivity and survey speed. The science goals are to better understand the ionized and neutral components of the cosmic web, and their evolution, through observations of Fast Radio Bursts and neutral hydrogen. Advances in the understanding of pulsars, molecules, radio galaxies and cosmic rays will also be achieved with this facility. The technology is based on cryogenic cooling of a large phased array feed. This receiver is a major advance over existing receivers on the Parkes and Australian SKA Pathfinder (ASKAP) telescopes.
