从前景污染物模拟非高斯性

Modelling non-Gaussianity from foreground contaminants

C. S. Carvalho

摘要:

我们介绍了一个通用类的模型charaterizing的非高斯特性的前景污染物在宇宙微波背景着眼于消除非原始的非高斯信号从原始的。这不仅对处理温度图很重要,而且对描述原始宇宙学扰动的性质和起源,从而建立早期宇宙理论也很重要。

英文摘要:

We introduce a general class of models for charaterizing the non-Gaussian properties of foreground contaminants in the cosmic microwave background with view towards the removal of the non-primordial non-Gaussian signal from the primordial one. This is important not only for treating temperature maps but also for characterizing the nature and origin of the primordial cosmological perturbations and thus establishing a theory of the early universe.
