Empirical Recovery of Local Velocity Structure in Nearby-Galaxy Redshifts: A Leave-One-Galaxy-Out Cross-validation

Version 3 substantially reframes and shortens the paper following additional reference-frame and peculiar-flow analysis. The revised version interprets the original predictive result as an empirical recovery of known local velocity structure rather than evidence for a new unexplained redshift phenomenon.

Abstract

Version 3 substantially reframes and shortens the paper following additional reference-frame and peculiar-flow analysis. The revised version interprets the original predictive result as an empirical recovery of known local velocity structure rather than evidence for a new unexplained redshift phenomenon.
