How this entity was disambiguated

This entity first appeared as the object of triple T2419191 — 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. 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.
B. Hubble sequence of galaxy classification
The Hubble sequence of galaxy classification is a morphological system that organizes galaxies into categories such as ellipticals, spirals, and irregulars based on their visual appearance.
C. Carnegie Irvine Galaxy Survey
The Carnegie Irvine Galaxy Survey is an astronomical project that provides detailed optical imaging and analysis of nearby galaxies to study their structure, formation, and evolution.
D. Carnegie-Spitzer-IMACS Survey
The Carnegie-Spitzer-IMACS Survey is an astronomical research project that combines infrared observations from the Spitzer Space Telescope with optical spectroscopy from the IMACS instrument to study the formation and evolution of galaxies across cosmic time.
E. New General Catalogue
The New General Catalogue is a comprehensive 19th-century astronomical catalog of deep-sky objects, including galaxies, nebulae, and star clusters, that remains widely used by astronomers today.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
