TL;DR
This paper derives the CMB temperature anisotropy correlation function considering the effects of a homogeneous magnetic field that breaks spatial isotropy, including off-diagonal correlations.
Contribution
It introduces a method to compute CMB anisotropies accounting for anisotropy caused by a homogeneous magnetic field with arbitrary orientation.
Findings
Derived the two-point correlation function including off-diagonal terms.
Showed how a homogeneous magnetic field affects CMB anisotropy patterns.
Provided a framework for analyzing anisotropic cosmological models.
Abstract
We derive the cosmic microwave background temperature anisotropy two-point correlation function (including off-diagonal correlations) from broken spatial isotropy due to an arbitrarily oriented homogeneous cosmological magnetic field.
