论文摘要
包装的超宽带映射阵列（PUMA）是在频率范围200-1100MHz的频率范围内运行的建议的低分辨率过境干涉射电望远镜。它丰富的科学投资组合将使用21厘米强度映射，检测一百万个快速无线电爆发，并监视数千个脉冲星，其中包括宇宙中的宇宙结构从红移z = 0.3到6。它将允许PUMA在三种不同领域的物理学（黑暗能源的物理学，宇宙通胀的物理学和时间域天体物理学）中推进科学。该文件是对无线电，毫米和亚毫米计观测值的回应（RFI），从2020年天文学和天体物理学的地面调查的地面（RMS）。我们介绍了PUMA的科学案例，开发路径和项目的主要风险。
The Packed Ultra-wideband Mapping Array (PUMA) is a proposed low-resolution transit interferometric radio telescope operating over the frequency range 200 - 1100MHz. Its rich science portfolio will include measuring structure in the universe from redshift z = 0.3 to 6 using 21cm intensity mapping, detecting one million fast radio bursts, and monitoring thousands of pulsars. It will allow PUMA to advance science in three different areas of physics (the physics of dark energy, the physics of cosmic inflation and time-domain astrophysics). This document is a response to a request for information (RFI) by the Panel on Radio, Millimeter, and Submillimeter Observations from the Ground (RMS) of the Decadal Survey on Astronomy and Astrophysics 2020. We present the science case of PUMA, the development path and major risks to the project.
