Low-frequency line temperatures of the CMB

TL;DR

This paper interprets low-frequency CMB line temperature anomalies as a phase boundary effect within SU(2) Yang-Mills thermodynamics, linking the baseline temperature to a phase transition and explaining excess signals via nonthermal photon fields.

Contribution

It introduces a novel interpretation of low-frequency CMB anomalies as a phase boundary effect in SU(2) Yang-Mills thermodynamics, connecting the baseline temperature to a critical phase transition.

Findings

Low-frequency CMB line temperature excess explained by evanescent nonthermal photons.

Baseline temperature identified with the critical temperature of a phase transition.

Phase-boundary interpretation accounts for radio-survey observations.

Abstract

Based on SU(2) Yang-Mills thermodynamics we interprete Aracde2's and the results of earlier radio-surveys on low-frequency CMB line temperatures as a phase-boundary effect. We explain the excess at low frequencies by evanescent, nonthermal photon fields of the CMB whose intensity is nulled by that of Planck distributed calibrator photons. The CMB baseline temperature thus is identified with the critical temperature of the deconfining-preconfining transition.
