How this entity was disambiguated

This entity first appeared as the object of triple T1014586 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Perseus–Pisces Supercluster
Context triple: [Laniakea Supercluster, neighboringStructure, Perseus–Pisces Supercluster]

A. Hydra–Centaurus Supercluster
The Hydra–Centaurus Supercluster is a massive nearby concentration of galaxy clusters that forms one of the dominant structures in our cosmic neighborhood and serves as a major component of the larger Laniakea Supercluster.
B. Laniakea Supercluster
Laniakea Supercluster is a vast cosmic structure encompassing the Milky Way and hundreds of thousands of other galaxies, forming one of the largest known galaxy superclusters in the observable universe.
C. Virgo Cluster
The Virgo Cluster is a massive, nearby galaxy cluster that serves as the central, dominant concentration of galaxies in our local region of the universe.
D. Centaurus A/M83 Group
The Centaurus A/M83 Group is a nearby galaxy group dominated by the massive galaxies Centaurus A and Messier 83, forming one of the closest large-scale neighbors to our own galactic neighborhood.
E. M81 Group
The M81 Group is a nearby collection of galaxies in the constellation Ursa Major, dominated by the large spiral galaxy Messier 81 and known for its interacting members and active star formation.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
