Concluding RemarksMorphology is an integral property of a galaxythat reflects its formation and evolutionprocess as well as its dynamical structures.The local background density is a criticalparameter that controls the galaxy morphology.There is no difference between the dwarfirregulars and blue dwarf ellipticals except forthe apparent roundness. Thus, apparent shape does not play decisive roles in defining galaxy morphology.
In case of satellite galaxies

Need more versatile classifier todifferentiate barred galaxies from non-barred ones and lenticulars fromellipticals.
