B模偏振的标度律和求和定则

Scaling laws and sum rules for the B-mode polarization

Massimo Giovannini

摘要:

研究了随机法拉第速率为平稳、随机和马尔可夫时微波背景极化各向异性的形成。极化功率谱及其非线性组合的标度特性被仔细检查作为共动频率的函数。有人认为,同时测量E-模式和B-模式光谱的给定实验的每个频率通道可以在这个框架中进行分析,其目的是在模型无关的角度测试偏振的物理起源。

英文摘要:

The formation of the microwave background polarization anisotropies is investigated when the stochastic Faraday rate is stationary, random and Markovian. The scaling properties of the polarization power spectra and of their nonlinear combinations are scrutinized as a function of the comoving frequency. It is argued that each frequency channel of a given experiment measuring simultaneously the E-mode and the B-mode spectra can be analyzed in this framework with the aim of testing the physical origin of the polarization in a model-independent perspective.
