Dwarf galaxies, the low‑mass, low‑luminosity systems that dominate the Universe’s galaxy population by number, are crucial to our understanding of galaxy formation and evolution. As darkmatter dominated, pristine primordial systems, they provide a unique probe into models of structure formation at the extremes. Knowledge of the abundances, distributions and structures of dwarf galaxies in all density environments contribute some of the strongest critical constraints on cosmological models, including the nature of dark matter, and key indications of how our Universe evolved. At present, most research into the detailed properties of dwarf galaxies focuses on those in the Local Group, or in nearby galaxy clusters. More recent wide‑field surveys also suffer from limitations in both their ability to distinguish the dwarfs from the background galaxies and in their characterisation and their internal structures and components.
