Cosmicflows-3：冷斑驱逐器？
Cosmicflows-3: Cold Spot Repeller?
摘要：
在z~0.1范围内的三维引力速度场已经用Wiener滤波方法模拟，并应用于Cosmicflows-3星系距离汇编。主要特征是一个吸引盆地和两个排斥盆地。主要的吸引盆地是星系沙普利集中的延伸。其中一个斥力盆，即偶极子斥力盆，位于宇宙微波背景偶极子的反顶点附近。另一个斥力盆地是在接近宇宙微波背景中“冷点”不规则性的方向上。据推测，一个巨大的空洞可能有助于从综合萨克斯-沃尔夫效应冷点的振幅。
英文摘要：
The three-dimensional gravitational velocity field within z~0.1 has been modeled with the Wiener filter methodology applied to the Cosmicflows-3 compilation of galaxy distances. The dominant features are a basin of attraction and two basins of repulsion. The major basin of attraction is an extension of the Shapley concentration of galaxies. One basin of repulsion, the Dipole Repeller, is located near the anti-apex of the cosmic microwave background dipole. The other basin of repulsion is in the proximate direction toward the 'Cold Spot' irregularity in the cosmic microwave background. It has been speculated that a vast void might contribute to the amplitude of the Cold Spot from the integrated Sachs-Wolfe effect.
