Examples of dwarf galaxy candidates of different types. From top left to bottom right: Nucleated dE with an elongated substructure connecting to the nucleus, possibly a signature of a GC migration and merging with the NSC; a traditional nucleated dE; a dI with clumps of star formation extending beyond the diffuse component; a pair of interacting dwarfs; a dI with a diffuse blue centre; a dI in superposition with a more distant spiral galaxy (having a spectroscopic redshift of z = 0.388); a blue-cored dE; a dE with a spectroscopic redshift of z = 0.0272 (or a distance of about 120 Mpc) showing a double nucleus with inner ‘S-shape’ features, likely associated with a NSC-NSC merger event; and a group of three dwarfs situated within a 30″ radius. The images are approximately 11″ × 11″ in size, except the image in the middle which is 2′×2′, and north is up and east to the left.
