Ivison, R., Lewis, A., Weiss, A., Arumugam, V., Simpson, J., Holland, W., …Wardlow, J. (2016). The Space Density of Luminous Dusty Star-forming Galaxies at z > 4: SCUBA-2 and LABOCA Imaging of Ultrared Galaxies from Herschel-ATLAS. Astrophysical Journal, 832(1), Article 78. https://doi.org/10.3847/0004-637x/832/1/78

Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at z > 4, most of them significantly amplified by gravitational lensing. Here, we have increased the number of such DSFGs substantially, selecting galaxies from the uni...
