Abstract (from CDS):

We report the spectroscopic confirmation of a submillimeter galaxy (SMG) at z=4.547 with an estimated LIR= (0.5-2.0)x1013 L☉. The spectra, mid-IR, and X-ray properties indicate the bolometric luminosity is dominated by star formation at a rate of >1000 M☉/yr. Multiple, spatially separated components are visible in the Lyα line with an observed velocity difference of up to 380 km/s and the object morphology indicates a merger. The best-fit spectral energy distribution and spectral line indicators suggest the object is 2-8 Myr old and contains >1010 M☉ of stellar mass. This object is a likely progenitor for the massive early-type systems seen at z∼2.
