Conventional research on distant galaxies have been carried out mainly with visible light and near infrared light. However, it is possible that many galaxies in the universe have been overlooked as much of that radiation is largely absorbed by cosmic dust. That is why millimeter and submillimeter wave observations are important. Stellar light absorbed by dust is reradiated from the dust as millimeter/submillimeter waves. Therefore galaxies, even those which it has not been possible to observe wi...
