2002年9月至2004年5月期间，使用宇宙背景成像仪对宇宙微波背景进行了偏振观测，对E模式偏振进行了显着检测，并揭示了偏振发射的角功率谱，其峰和谷的相位相对于总强度谱的峰和谷移动了半个周期。观测到的偏振光谱的相位与根据总强度光谱预测的相位之间的关键一致性为宇宙学的标准模型提供了支持，在该模型中，暗物质和暗能量是主要成分，几何形状接近平坦，原始密度波动主要是绝热的，其物质功率谱与暴胀宇宙学模型相当。
Polarization observations of the cosmic microwave background with the Cosmic Background Imager from September 2002 to May 2004 provide a significant detection of the E-mode polarization and reveal an angular power spectrum of polarized emission showing peaks and valleys that are shifted in phase by half a cycle relative to those of the total intensity spectrum. This key agreement between the phase of the observed polarization spectrum and that predicted on the basis of the total intensity spectrum provides support for the standard model of cosmology, in which dark matter and dark energy are the dominant constituents, the geometry is close to flat, and primordial density fluctuations are predominantly adiabatic with a matter power spectrum commensurate with inflationary cosmological models.
