Cosmic motion aligns with the cosmic microwave background dipole across high-redshift quasars, supporting the foundational cosmological principle over vast cosmological distances.
An inferred velocity of 196 km/s demonstrates 2σ agreement with the expected cosmic microwave background dipole, contrasting with earlier radio galaxy tensions.
Blind analysis of spectroscopic data using realistic mock catalogs validates tomographic dipole estimators, yet unresolved systematic errors in low-redshift BOSS samples require caution.
