标题： 25 years of Cosmic Microwave Background research at INPE

摘要： 本文是关于INPE过去25年宇宙微波背景活动的报告。 从利用气球飞行测量由于地球在CMB辐射场中的运动引起的二极子各向异性开始，其辐射计是COBE卫星上的DMR辐射计的原型，该小组成员在90年代同时从事CMB各向异性和前景测量。 在2000年代，重点转向极化测量和数据分析，主要集中在地图清理、非高斯性研究和前景特征分析。 显示英文摘要

摘要： This article is a report of 25 years of Cosmic Microwave Background activities at INPE. Starting from balloon flights to measure the dipole anisotropy caused by the Earth's motion inside the CMB radiation field, whose radiometer was a prototype of the DMR radiometer on board COBE satellite, member of the group cross the 90s working both on CMB anisotropy and foreground measurements. In the 2000s, there was a shift to polarization measurements and to data analysis, mostly focusing on map cleaning, non-gaussianity studies and foreground characterization.
