LEDA 2108986
Galaxy in the constellation Boötes
LEDA 2108986,[3] also known by its Case Western Reserve University designation "Case Galaxy 611" (CG 611),[4] is an extremely isolated, early-type dwarf galaxy[5][6][7] with an embedded spiral structure residing in what is likely an intermediate-scale disk.[8] The galaxy was discovered in 1987 by Sanduleak and Pesch, and is located at a distance of about 45.7 megaparsecs (149,000,000 ly) in the Boötes Void and has no significant neighbours within 2.5 Mpc.
The galaxy may be a counterpart to the rectangular-shaped galaxy LEDA 74886, in that they both appear to contain an intermediate-scale disk. In the case of LEDA 74886, that disk is orientated edge-on to our line-of-sight. The "early-type galaxy" class is commonly known to contain elliptical galaxies (E) with no substantial stellar disk (perhaps just a small nuclear disk) and lenticular galaxies (S0) with their large-scale disks that dominate the light at large radii. Bridging these two types of galaxies are the ES galaxies[9] with their intermediate-scale disks, referred to as "Ellicular" galaxies in recent works.[8]
