In the local universe most stars are formed in disk galaxies with the bulk of their emission at ultraviolet/optical wavebands. Extremely dusty galaxies, with an enhanced emission at infrared (IR) wavelengths, are rare “freaks” in today’s universe but dominate the co-moving energy density in the distant universe. With unusually high star formation rates, these galaxies can build the stellar bulk of a massive galaxy in under a few hundred million years, providing a long-sought answer to the origin of today’s most massive galaxies. These dusty systems have also been targets of deep observing campaigns to trace the growth of large-scale structures in the early universe. I will provide a review on dusty star-forming galaxies in the distant universe in the light of ongoing and future observing campaigns with state-of-the-art instruments (i.e., 10m-class telescopes, current and upcoming space telescopes).
