我们回顾了最近在宇宙微波背景的温度各向异性图中发现的大尺度异常。这些包括CMB各向异性的最大模式彼此之间以及与太阳系的几何和运动方向的对准,以及在这些最大尺度上异常低的功率。我们讨论了这些发现与来自标准膨胀宇宙学的预期有关的问题,它们的统计学意义,研究它们的工具,以及解释它们的各种尝试。
We review the recently found large-scale anomalies in the maps of temperature anisotropies in the cosmic microwave background. These include alignments of the largest modes of CMB anisotropy with each other and with geometry and direction of motion of the solar ssystem, and the unusually low power at these largest scales. We discuss these findings in relation to expectation from standard inflationary cosmology, their statistical significance, the tools to study them, and the various attempts to explain them.
