[en] LSB galaxies make up a significant amount of the luminosity density of the local universe. They have to be considered when building complete and homogeneous catalogs of galaxies. Their low surface brightness suggests a different formation and evolution process compared to more typical high-surface-brightness galaxies. LSB galaxies may hold important clues about the nature of dark matter, which is believed to be responsible for the observed rotation curves of galaxies, including LSB galaxies. Installed on the mountain of northern India, the ILMT provides surveys in g’, r’ and i’ bands, which makes it possible to study the difference between red and blue LSB galaxies based on the g−r colour criteria. Additionally, by investigating the surface brightness properties of LSB galaxies, the distribution and properties of dark matter in the universe can be learned in further research.
