EDGES: An Ultra-Clean Spectrometer for Fundamental Measurements of Cosmological Reionization and the Dark Ages

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目支持设计和开发一种灵敏的宽带天线和接收器，用于观察高红移中性氢在整个再电离时期的角度和红移分布。该系统工作在45 - 200 MHz范围内，将提供极高的动态范围，用于在强自然和人造无线电环境中观测相对较弱的氢信号。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The project supports the design and development of a sensitive, broadband antenna and receiver to observe the distribution in angle and redshift of highly redshifted neutral hydrogen, throughout the epoch of reionization. The system, operating in the 45 - 200 MHz range, will offer extremely high dynamic range for observing relatively weak hydrogen signatures within the strong natural and man-made radio environment.
