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.

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.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Tully-Fisher relation distances Description of subject: Tully-Fisher relation distances are galaxy distance measurements derived from the empirical correlation between a spiral galaxy’s luminosity and its rotational velocity.
