How this entity was disambiguated
This entity first appeared as the object of triple T18887564 — 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.
OIII
OIII is the ICAO airport code for Mehrabad International Airport in Tehran, Iran.
-
B.
H-alpha
H-alpha is a specific deep-red spectral emission line of hydrogen widely used in astronomy to study ionized gas regions, star formation, and solar activity.
-
C.
O3
O3 is the third observing run of the LIGO–Virgo gravitational-wave detector network, during which numerous gravitational-wave events from compact binary mergers were detected.
-
D.
Blue III
Blue III is an abstract painting by Spanish artist Joan Miró, known for its bold use of color and biomorphic forms characteristic of his mature surrealist style.
-
E.
Lyman-β
Lyman-β is the second spectral line in the hydrogen Lyman series, corresponding to an electron transition from the fourth to the first energy level and emitting ultraviolet radiation.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
