An international team of astronomers has identified nearly 21,000 low-surface-brightness galaxies (LSBGs) in the Dark Energy Survey (DES). The detection of such a huge sample could be essential to improving our knowledge about how LSBGs form and evolve. The finding is reported in a paper published June 8 on arXiv.org.
