Dusty star-forming galaxies are galaxies that are actively forming new stars and are characterized by high levels of dust obscuring their star-forming regions. The dust in these galaxies absorbs the ultraviolet and optical light emitted by young, hot stars, re-radiating it at longer infrared wavelengths. This makes dusty star-forming galaxies particularly bright in the infrared spectrum. Studying these galaxies can provide insights into the physical processes involved in star formation, as well as the role of dust in shaping the properties of galaxies. Dusty star-forming galaxies are often found in the early universe, where the conditions are ideal for rapid star formation.
