Is the Cosmic "Axis of Evil" due to a Large-Scale Magnetic Field

TL;DR

This paper proposes that a large-scale cosmic magnetic field could explain the observed alignment of low multipoles in the CMB and galaxy spins, suggesting a common magnetic origin for these large-scale cosmic features.

Contribution

It introduces a novel mechanism linking cosmic magnetic fields to CMB anisotropies and galaxy spin alignments, providing a potential explanation for the 'Axis of Evil' phenomenon.

Findings

Large-scale magnetic fields can align electron cyclotron orbits in hot plasmas.

Inverse Compton scattering imprints this alignment onto the CMB.

Galaxy spins are aligned with the proposed cosmic magnetic field.

Abstract

I propose a mechanism that would explain the near alignment of the low order multipoles of the cosmic microwave background (CMB). This mechanism supposes a large-scale cosmic magnetic field that tends to align the cyclotron orbit axes of electrons in hot plasmas along the same direction. Inverse Compton scattering of the CMB photons then imprints this pattern on the CMB, thus causing the low- multipoles to be generally aligned. The spins of the majority of spiral galaxies and that of our own Galaxy appear to be aligned along the cosmic magnetic field.
