CMB中的大角度异常

Large-angle anomalies in the CMB

Craig J. Copi, Dragan Huterer, Dominik J. Schwarz, Glenn D. Starkman

摘要:

我们回顾了最近在宇宙微波背景温度各向异性图中发现的大规模异常。这些包括CMB各向异性的最大模式相互之间的对齐,以及与太阳系的几何形状和运动方向的对齐,以及在这些最大尺度上异常低的功率。我们讨论这些发现与标准暴胀宇宙学的期望,它们的统计意义,研究它们的工具,以及解释它们的各种尝试。

英文摘要:

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 System, 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.
