Low Frequency Measurements of the Cosmic Microwave Background Radiation

这个项目将测量宇宙微波的形状 背景辐射（CMBR）在四个频率，1.5 GHz，3.7 GHz， 10 GHz和90 GHz。 与黑体光谱的偏差 据报道，如果得到证实，这将改变我们对如何 宇宙形成了。 南极是最好的地点 由于极度寒冷，因此干燥， 大气层，以及仪器观察一部分的能力 天空中不断地通过一个恒定的厚度， 气氛 它也是地球上无线电最安静的地方 频率选择 该项目还将量化 测量大气噪声，这将是非常有价值的， 未来的调查员

This project will measure the shape of the Cosmic Microwave Background Radiation (CMBR) at four frequencies, 1.5 GHz, 3.7 GHz, 10 GHz, and 90 GHz. Deviations from a blackbody spectrum have been reported, which if confirmed would alter our view of how the universe was formed. The South Pole is the best site for this measurement due to the extremly cold, and therefore dry, atmosphere, and the ability of the instruments to view one portion of the sky continuously through a constant thickness of the atmosphere. It is also the quietest spot on earth for the radio frequencies chosen. The project will also make quantitative measurements of atmospheric noise that will be of great value for future investigators.
