High-Resolution Imaging from Mauna Kea: Morphology of Butcher-Oemler Galaxies
Abstract
CCD images have been obtained of four bona fide blue Butcher-Oemler galaxies. Two are members of A370 (z = 0.38), one belongs to A963 (z = 0.2l), and the fourth belongs to C10024+16 (z = 0.39). All four galaxies appear to be disk systems, and several show signs of structural asymmetry. Two of the four blue galaxies show spiral structure, and two may have close companion galaxies.
