ABSTRACT:

The characterisation of the star-formation history (SFH) of the Universe (integral of the luminosity function) is an ultimate goal of cosmology, as this tells us when and where all stars were formed. This is usually attempted using optical surveys, missing dusty galaxies, which is problematic, as the extragalactic background light indicates that half of the stellar emission in the Universe is reprocessed by dust. I will review what we know about dusty star-forming galaxies, their properties, luminosity functions and contributions to the cosmic SFHs across z=0 to z=5. I will also show the preliminary results from the emerging instruments and show the future prospects in studying dust in distant galaxies.
