How this entity was disambiguated

This entity first appeared as the object of triple T5410706 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A. A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae
"A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae" is Edwin Hubble’s landmark 1929 paper that established the linear relationship between galaxies’ distances and their recessional velocities, providing the first strong evidence for the expanding universe.
B. Faber–Jackson relation paper
The Faber–Jackson relation paper is a landmark astrophysics publication that established a correlation between the luminosity and stellar velocity dispersion of elliptical galaxies, providing key insights into their structure and evolution.
C. Faber–Jackson relation
The Faber–Jackson relation is an empirical correlation in astronomy that links the luminosity of an elliptical galaxy to the velocity dispersion of its stars, providing a key tool for estimating galactic distances and masses.
D. Tolman surface brightness test
The Tolman surface brightness test is an observational cosmology method that checks whether the universe is expanding by examining how the surface brightness of distant galaxies diminishes with redshift.
E. Zwicky catalog of galaxies
The Zwicky catalog of galaxies is an influential astronomical catalog compiled by Swiss astronomer Fritz Zwicky that systematically lists and classifies thousands of galaxies and galaxy clusters.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
