A unified description for dipoles of the fine-structure constant and SnIa Hubble diagram in Finslerian universe

Abstract

We propose a Finsler spacetime scenario of the anisotropic universe. The Finslerian universe requires both the fine-structure constant and accelerating cosmic expansion have dipole structure, and the directions of these two dipoles are the same. Our numerical results show that the dipole direction of SnIa Hubble diagram locates at $(l,b)=(314.6^{\circ }\pm 20.3^{\circ },-11.5^{\circ }\pm 12.1^{\circ })$ with magnitude $B=(-3.60\pm 1.66)\times 10^{-2}$. And the dipole direction of the fine-structure constant locates at $(l,b)=(333.2^{\circ }\pm 8.8^{\circ },-12.7^{\circ }\pm 6.3^{\circ })$ with magnitude $B=(0.97\pm 0.21)\times 10^{-5}$. The angular separation between the two dipole directions is about $18.2^{\circ }$.
