Overview
- The measured anisotropy in radio‑galaxy counts is 3.7 times the standard‑model expectation, with a reported significance of 5.4σ.
- The study merges multiple radio surveys, including LOFAR, and accounts for multi‑component sources to produce more realistic uncertainties.
- The inferred motion aligns in direction with the cosmic microwave background dipole that implies about 369.8 km/s, but its amplitude is far larger.
- Independent quasar and infrared catalogs have shown a comparable dipole anomaly, which the authors cite as supporting evidence.
- The findings are published in Physical Review Letters, and the team urges independent replications and systematic audits before drawing theoretical conclusions.
