U.S.-Brazil Cooperative Science Program: Making Maps of theLow-Frequency Sky Brightness (Galactic Emmission Maps at Long-Wavelength)

这项来自美国-巴西合作科学计划的奖项将支持加州大学的乔治·F·斯穆特博士在大气科学方面的合作研究，伯克利和巴西圣何塞·多斯坎波斯国家佩斯基萨斯环境研究所(INPE)的Thyrso Villela博士。该项目将绘制南方天空的地图，作为制作高质量银河系发射地图的计划的一部分。这一合作将伯克利小组在研究宇宙本底辐射方面公认的专门知识与巴西方面提供的进入领土和高增益设备结合在一起。该项目将首先以15至10度的角度分辨率，然后以更高的分辨率对400至1000兆赫范围内的差值和绝对天空亮度进行光谱测量。这些测量将研究银河系、河外和宇宙辐射的光谱。这项研究将为下一代高精度测量宇宙微波背景辐射(CMBR)的甚低频谱提供基础，并允许重新解释低频CMBR在过去十年中进行的光谱测量。*//

This award form the U.S.-Brazil Cooperative Science Program will support collaborative research in atmospheric sciences to be carried out by Dr. George F. Smoot of the University of California, Berkeley and Dr. Thyrso Villela of the Instituto Nacional Pesquisas Espaciais (INPE) at San Jose dos Campos, Brazil. The project will map the southern sky as part of a program to make high quality maps of galactic emission. This collaboration combines the acknowledged expertise of he Berkeley group in studying cosmic background emission with the access to territory and high gain equipment afforded by the Brazilian side. The project will make spectral measurements of the differential and absolute sky brightness over the 400 to 1000 MHz range first with 15 to 10 degree angular resolution and then at higher resolution. These measurements will study the spectrum of galactic, extragalactic and cosmic radiation. The study will provide the basis for the next generation of high-precision measurements of the very low-frequency spectrum of the cosmic microwave background radiation (CMBR) and allow the reinterpretation of low-frequency CMBR spectrum measurements made over the past decade. ***//
