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_{sun}_/yr), stellar (~3.6x10^11^M_{sun}_) and dust (~6.7x10^8^M_{sun}_) masses, extinction (A_V_~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%).2010ApJ...712..942Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/712/942CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)J/MNRAS/413/2314 : Radio and mid-IR counterpart of submm galaxies (Biggs+,J/MNRAS/415/1479 : LESS photometric redshift survey (Wardlow+, 2011)J/ApJ/699/1610 : Spitzer survey of submillimeter galaxies (Hainline+, 2009)J/other/Nat/458.737 : BLAST sources at 250, 350 and 500um (Devlin+, 2009)J/A+A/496/45 : CO maps of three lensed submillimetre galaxies (Knudsen+,J/ApJ/622/772 : Redshift survey of submillimeter galaxies (Chapman+, 2005)J/ApJ/626/L15 : Templates for photometric redshifts of submm sourcesJ/AJ/127/180 : The Hawaii Hubble Deep Field North (Capak+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/712/942https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/712/942http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/712/942https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/712/942https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/712/942http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/712/942GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/712/942/smg (Submillimeter-selected galaxies (SMGs) sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/712/942/smg?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/712/942/smg?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/712/942/smg?GETtext/xml+votable180.050000true53.1220417-27.938750.0055555555555555566/11252 11626 27258 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/712/942?format=asciiOpticalRadiodefaultJ/ApJ/712/942/smgSubmillimeter-selected galaxies (SMGs) samplerecnoRecord number assigned by the VizieR team.
