Overview

The Terzan Catalogue consists of 11 globular clusters discovered by Agop Terzan using infrared observations made at Lyon Observatory in France during the 1960s and early 1970s. Most of the globular clusters are located in the constellations of Sagittarius and Scorpius, near the Milky Way's Galactic Center; Terzan 7 and Terzan 8 are most likely part of the Sagittarius Dwarf Elliptical Galaxy. Although all of the Terzan Catalogue objects were originally presumed to be globular clusters, there have been recent suggestions (by Mikkel Steine and others) that some of them may in fact be open clusters.[1]

Since the original Terzan 11 is a duplicate of Terzan 5, more recent versions of the catalogue have renamed the original Terzan 12 as Terzan 11.[2]

The catalogue is based on scientific papers published by Agop Terzan in 1966 (for Terzan 1),[3] 1967 (for Terzan 2),[4] 1968 (for Terzan 3 to 8),[5] and 1971 (for Terzan 9 to 12).[6]
