| 1. | It is part of a galaxy group called Abell 2052.
Ce groupe fait partie d'un ensemble plus vaste, l'amas galactique Abell 194,. |
| 2. | This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.
Cet amas regroupe les galaxies spirales M65, M66, et NGC 3628. |
| 3. | Superclusters are frequently subdivided into groups of clusters called galaxy groups and clusters.
Les superamas sont fréquemment subdivisés en groupes d'amas appelés nuages de galaxies. |
| 4. | They are quite common in galaxy groups and clusters, and are usually companions to other galaxies.
On en retrouve souvent dans les amas de galaxies et elles sont souvent les compagnons d'autres galaxies. |
| 5. | In the 1980s, the Lyons Groups of Galaxies listed 485 galaxy groups with 3,933 member galaxies.
Dans les années 1980, le Lyons Groups of Galaxies recense 3 933 galaxies réparties dans 485 groupes. |
| 6. | Clusters of galaxies are formed by the merger of smaller units of matter, such as galaxy groups or individual galaxies.
Les amas de galaxies sont formés par la fusion des unités plus petites de la matière, tels que les groupes de galaxies ou galaxies individuelles. |
| 7. | The brightest member in this galaxy group is questionable and partly depends on the analysis used to determine group members.
Le membre le plus brillant de cet amas de galaxies est sujet à controverse et dépend partiellement sur l'analyse utilisée pour déterminer les membres du groupe. |
| 8. | Abell divided the clusters into six "richness groups", depending on the number of galaxies in a given cluster that lie within the magnitude range m3 to m3+2 (the average number of galaxies per cluster for the entire catalog was 64): Group 0: 30–49 galaxies Group 1: 50–79 galaxies Group 2: 80–129 galaxies Group 3: 130–199 galaxies Group 4: 200–299 galaxies Group 5: more than 299 galaxies Compactness: A cluster must be sufficiently compact that its fifty or more members lie within one "counting radius" of the cluster's centre.
