| 英文摘要 | We propose a framework of Finsler space-time to explain the observed parity asymmetry and the power deficit in the low-l (2 <= l <= 29) multipole range of cosmic microwave background (CMB) temperature anisotropies. In the 3 + 1 dimensional space-time, the three-dimensional space is described by a Randers-Finsler space, which is spatially irreversible, inducing the parity asymmetry in the CMB angular power spectrum. We estimate the constraints on the two parameters introduced by Finsler space-time via analysing the low-l angular power spectrum in PLANCK 2015 CMB temperature data. We see that the low-l. power suppression in the CMB temperature anisotropies can also be resolved in this scenario. Our study shows that the two low-l. anomalies, i.e. parity asymmetry and power deficit, may have a common origin. |
