How this entity was disambiguated
This entity first appeared as the object of triple T9453581 — 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.
Bardeen potential
The Bardeen potential is a gauge-invariant gravitational potential used in cosmological perturbation theory to describe scalar metric fluctuations in the early universe.
-
B.
Hayward black hole model
The Hayward black hole model is a theoretical, regular (non-singular) black hole solution in general relativity that modifies the central singularity with a de Sitter core, often studied as an alternative to classical black hole models.
-
C.
Bardeen black hole model
The Bardeen black hole model is a theoretical proposal of a regular (non-singular) black hole solution in general relativity that avoids the central singularity by coupling gravity to nonlinear electrodynamics.
-
D.
Schwarzschild–Milne equations
The Schwarzschild–Milne equations are fundamental integro-differential equations in radiative transfer theory that describe the propagation and scattering of radiation through a plane-parallel, absorbing and emitting medium.
-
E.
Zeldovich–Novikov theory of black holes
The Zeldovich–Novikov theory of black holes is a foundational theoretical framework that analyzes the formation, structure, and astrophysical properties of black holes within the context of general relativity and high-energy astrophysics.
- 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.
