CMB斑点的计数响应模型

Count response model for the CMB spots

Massimo Giovannini

摘要:

在暴胀膨胀的一个阶段中产生的曲率量子的统计数据被用来推导出一个计数响应模型的大尺度声子确定,在和谐的知识,温暖和冷却点的大尺度温度不均匀性。计数统计的多重性分布被证明是一般过度分散与传统的泊松回归。下面推导出的广义计数响应模型适应了高多重性范围内的过量相关性,并提示了对由高角分辨率和对每个像素的温度变化的高灵敏度的仪器收集的即将到来的数据的专门分析。

英文摘要:

The statistics of the curvature quanta generated during a stage of inflationary expansion is used to derive a count response model for the large-scale phonons determining, in the concordance lore, the warmer and the cooler spots of the large-scale temperature inhomogeneities. The multiplicity distributions for the counting statistics are shown to be generically overdispersed in comparison with conventional Poissonian regressions. The generalized count response model deduced hereunder accommodates an excess of correlations in the regime of high multiplicities and prompts dedicated analyses with forthcoming data collected by instruments of high angular resolution and high sensitivity to temperature variations per pixel.
