重新评估CMB中霍金点的证据
Re-evaluating evidence for Hawking points in the CMB
摘要：
我们调查最近的索赔检测“霍金点”（在天空中的位置与异常大的温度梯度环之间）在宇宙微波背景（CMB）温度图在99.98%的置信水平。我们发现，在对环的大小进行边缘化之后，在普朗克卫星地图中仅以87%的置信水平检测到过量（即，略大于1 $σ$）。因此，我们的结论是，没有统计学上显著的证据表明，在CMB中存在霍金点。
英文摘要：
We investigate recent claims for a detection of "Hawking points" (positions on the sky with unusually large temperature gradients between rings) in the cosmic microwave background (CMB) temperature maps at the 99.98% confidence level. We find that, after marginalization over the size of the rings, an excess is detected in Planck satellite maps at only an 87% confidence level (i.e., little more than 1$σ$). Therefore, we conclude that there is no statistically significant evidence for the presence of Hawking points in the CMB.
