“暗流”的统计意义
The Statistical Significance of the "Dark Flow"
摘要:
我们重新审视了Kashlinsky等人(2009)提出的“暗流”的统计学意义。我们没有发现大量流动的统计学显著检测。相反,我们发现,在本分析中使用的8个WMAP通道之间的CMB相关性降低了检测的推断意义为0.7σ。
英文摘要:
We revisit the statistical significance of the "dark flow" presented in Kashlinsky et al. (2009). We do not find a statistically significant detection of a bulk flow. Instead we find that CMB correlations between the 8 WMAP channels used in this analysis decrease the inferred significance of the detection to 0.7σ.
