CMB Anomalies from Self-Organized Criticality

Abstract

The power spectrum of the cosmic microwave background (CMB) quantifies the distribution of relic radiation left over from the early Universe. As of today, CMB data acquired by Planck and WMAP satellites exhibit certain anomalies that challenge the standard model of cosmology (ΛCDM). The goal of this brief report is to sketch up an intriguing connection between CMB anomalies and self-organized criticality (SOC). Our proposal bypasses the interpretation of CMB anomalies based on Loop Quantum Cosmology (LQC).
