Description

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_{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%).
