标题： Evidence for Scale-Scale Correlations in the Cosmic Microwave Background Radiation

摘要： 我们对COBE-DMR 4年天空图进行了离散小波分析，并发现在大约11到22度的角尺度上，只有在以北银极为中心的DMR面中存在显著的尺度-尺度相关性。 这种非高斯特征既不是来自已知的前景，也不是来自相关的噪声图，也不符合DMR图中残余系统误差的上限。 要么是尺度-尺度相关性是由未知的前景污染或在高达22度的角尺度上的系统误差引起的，要么标准暴胀加冷暗物质范式在$> 99%$置信水平上被排除。 显示英文摘要

摘要： We perform a discrete wavelet analysis of the COBE-DMR 4yr sky maps and find a significant scale-scale correlation on angular scales from about 11 to 22 degrees, only in the DMR face centered on the North Galactic Pole. This non-Gaussian signature does not arise either from the known foregrounds or the correlated noise maps, nor is it consistent with upper limits on the residual systematic errors in the DMR maps. Either the scale-scale correlations are caused by an unknown foreground contaminate or systematic errors on angular scales as large as 22 degrees, or the standard inflation plus cold dark matter paradigm is ruled out at the $> 99%$ confidence level.
