Cosmic evolution of submillimeter galaxies and their contribution to stellar mass assembly

Understand

The nature of galaxies selected at submillimeter wavelengths (SMGs, S_850 > 3 mJy), some of the bolometrically most luminous objects at high redshifts, is still elusive.

• In particular their star formation histories and source of emission are not accurately constrained.
• In this paper we introduce a new approach to analyse the SMG data.
• Namely, we present the first self-consistent UV-to-radio spectral energy distribution fits of 76 SMGs with spectroscopic redshifts using all photometric datapoints from ultraviolet to radio simultaneously.
