一般球对称时空中积分Sachs-Wolfe效应的规范不变处理

Gauge-invariant treatment of the integrated Sachs-Wolfe effect on general spherically symmetric spacetimes

Kenji Tomita

摘要:

在Gerlach-Sengupta规范不变微扰理论的基础上,导出了一般球对称时空中中心观测者的积分Sachs-Wolfe效应公式。这将有助于比较研究Lemaitre-Tolman-Bondi宇宙学模型中积分Sachs-Wolfe效应的理论和观测方面,这些模型已被注意到,通过解释没有宇宙学常数的表观加速度。

英文摘要:

On the basis of the Gerlach-Sengupta theory of gauge-invariant perturbations, a formula of the integrated Sachs-Wolfe effect for a central observer is derived on general spherically symmetric spacetimes. It will be useful for comparative studies of theoretical and observational aspects of the integrated Sachs-Wolfe effect in the Lemaitre-Tolman-Bondi cosmological models which have been noticed by explaining the apparent acceleration without cosmological constant.
