Abstract:
    The existence of submillimeter-selected galaxies (SMGs) at redshifts
    z>4 has recently been confirmed. Simultaneously using all the
    available data from UV to radio, we have modeled the spectral energy
    distributions of the six known spectroscopically confirmed SMGs at
    z>4. We find that their star formation rates (average
    ∼2500M☉/yr), stellar (∼3.6x1011M☉) and dust
    (∼6.7x108M☉) masses, extinction (AV∼2.2mag), and gas-to-dust
    ratios (∼60) are within the ranges for 1.7<z<3.6 SMGs. Our analysis
    suggests that infrared-to-radio luminosity ratios of SMGs do not
    change up to redshift ∼5 and are lower by a factor of ∼2.1 than the
    value corresponding to the local IR-radio correlation. However, we
    also find dissimilarities between z>4 and lower-redshift SMGs. Those
    at z>4 tend to be among the most star-forming, least massive, and
    hottest (∼60K) SMGs and exhibit the highest fraction of stellar mass
    formed in the ongoing starburst (∼45%).

Description:
    In Michalowski et al. (2010A&A...514A..67M), we analyzed the full
    UV-to-radio spectral energy distributions (SEDs) of 76 SMGs from the
    Chapman et al. (2005, Cat. J/ApJ/622/772) sample with spectroscopic
    redshifts up to z<3.6. Here, we extend that study by analyzing the
    sample of six spectroscopically confirmed SMGs at z>4. The
    photometric data are presented in Tables 1 and 2.
