Substructures in two isolated and quenched void dwarf galaxies. Left: DECaLs r-band data for two examples of the main sample where isophotes of elliptical models are overplotted in red. The middle panel shows the constructed elliptical model for each of the galaxies. Right: Residual images constructed from subtracting elliptical models from observations. The white contours are isophotes of the elliptical models. The dwarf galaxy shown in the top panels is nucleated, similar to the other 14 galaxies in the main sample. The dwarf in the bottom panels has a disk-like substructure, and three galaxies in the main sample exhibit such substructure.
