The Wide layer survey is deep enough to detect a large number of z~4 Lyman break galaxies and that allows us to trace the large-scale structure of the early Universe. We have identified more than 200 forming clusters at high significance (Toshikawa et al. 2017 arXiv:1708.09421)

Some of the nearby faint dwarf galaxies are known to be very diffuse. The nature of the diffuse object in this image is unclear, but it may be an extreme case of such a diffuse galaxy. Details can be found in Greco et al. 2018 (PASJ, 70, 19).
