Vaguely banana-shaped galaxies detected by JWST (top row) and simulations of how galaxies would look if formed under the influence of wave dark matter (row 2), warm dark matter (row 3) and cold dark matter (row 4) Alvaro Pozo et al. (2024)

Working out which types could help us understand how galaxies across the universe formed.
