How this entity was disambiguated
This entity first appeared as the object of triple T9793572 — 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.

Target entity: Navarro–Frenk–White profile Context triple: [Einasto profile, comparedTo, Navarro–Frenk–White profile]
-
A.
Einasto density profile
The Einasto density profile is a mathematical model used in astrophysics to describe how the density of dark matter and stars varies smoothly with distance from the centers of galaxies and galaxy clusters.
-
B.
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.
-
C.
Zeldovich approximation
The Zeldovich approximation is a cosmological model that provides a simple, first-order description of the growth of large-scale structure in the universe by tracking how matter elements move under gravity from initially small density perturbations.
-
D.
Zeldovich approximation in large-scale structure formation
The Zeldovich approximation in large-scale structure formation is a seminal analytical model in cosmology that predicts how small initial density perturbations in the early universe evolve into the cosmic web of sheets, filaments, and clusters of galaxies.
-
E.
Shapley Concentration
Shapley Concentration is one of the most massive known supercluster complexes of galaxies in the nearby universe, located in the constellation Centaurus.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

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
