Abelln.

Brit.

/ˈeɪbl/, U.S.

/ˈeɪb(ə)l/

Origin: From a proper name. Etymon: proper name Abell.

Etymology: < the name of George Ogden Abell (1927–83), U.S. astronomer, who compiled a catalogue of clusters of galaxies, published in 1958 (see Astrophysical Jrnl. Suppl. 3 211).

Astronomy.

1. With following numeral: any of certain galaxy clusters distinguished by their richness (i.e. the number and density of galaxies in their central regions) and listed by Abell in his catalogue.

ΚΠ

1959 Astrophysical Jrnl. 130 629 It has been listed by Abell (1958) (No. 2151 in his catalogue), and there is another irregular cluster, Abell No. 2152, 1°.3 south of it.

1989 J. Silk Big Bang (rev. ed.) xii. 266 (caption) The cluster is Abell 370 at a redshift of 0.17.

1995 Sci. News 6 May 287/1 The telescope captured 120 faint arclets fanning out like a spiderweb around the massive cluster of galaxies known as Abell 2218.

2004 B. Bunch & A. Hellemans Hist. Sci. & Technol. 674/1 One of the arcs, in Abell 370, is the image of a far-distant, unseen galaxy that has been distorted by a gravitational lens.

2. attributive and in the possessive. Designating rich galaxy clusters listed in Abell's catalogue; relating to such clusters. Frequently in Abell cluster.

1964 Monthly Notices Royal Astron. Soc. 128 106 In neither analysis was any allowance made for the variation of the apparent size of Abell's clusters with distance.

1977 Astrophysical Jrnl. 215 714 According to Abell's richness criteria, R=2 clusters should have 1.6 times as many galaxies as R=1 clusters..,at least at r ≲ 1.5h⁻¹Mpc, the Abell radius.

1993 Proc. National Acad. Sci. U.S.A. 90 4796/2 A Hubble diagram for the first-ranked galaxies in these Abell clusters is shown in Fig. 7.

2008 M. S. Longair Galaxy Formation (ed. 2) iv. 131 Several arcs can be observed more or less centred on the core of the Abell cluster.
