论文摘要
在宇宙学的标准模型中，宇宙微波背景（CMB）的天空预计不会显示对称偏好。在我们先前的研究之后，我们探讨了ESA Planck探针最新的全途径CMB温度图中的任何特殊奇偶校验偏好的存在。具体来说，在这项工作中，我们将通过Planck 2015数据中的CMB的偶数和奇数多物探测（a）对称性。此外，我们还通过分析$ l+m $ =偶数或奇数模式组合中的功率来评估对镜像对称性的任何特定偏好（a）对称性。
In the standard model of cosmology, Cosmic Microwave Background (CMB) sky is expected to show no symmetry preferences. Following our previous studies, we explore the presence of any particular parity preference in the latest full-mission CMB temperature maps from ESA's Planck probe. Specifically, in this work, we will probe (a)symmetry in power between even and odd multipoles of CMB via it's angular power spectrum from Planck 2015 data. Further we also assess any specific preference for mirror parity (a)symmetry, by analysing the power contained in $l+m$=even or odd mode combinations.
