On the Azimuthal Alignment of Quasars Spin Vector in Large Quasar Groups and Cosmic Strings

TL;DR

This paper presents evidence that quasar spin vectors are aligned in large groups, likely due to early universe cosmic string effects, with stronger alignment expected at higher redshifts.

Contribution

It provides observational evidence of quasar spin alignment linked to cosmic strings, suggesting a cosmological origin of this phenomenon.

Findings

Quasar spin vectors show azimuthal alignment in large groups.

Alignment strength increases with redshift.

Potential connection to cosmic string symmetry breaking.

Abstract

We find evidence of the alignment of the azimuthal angle of the spin vectors of quasars in large quasar groups of different redshift. This effect is probably of cosmological origin and could be explained by symmetry breaking of the scalar-gauge field of cosmic strings in the early universe. It is expected that this effect will be more profound for higher redshift.
