Abstract
Thanks to pre-selection techniques from large surveys made with infrared/sub-mm telescopes (e.g. Donevski et al. 2018), a huge progress in unveiling the high-z tail (z > 4) of dusty star-forming galaxies (DSFGs) has been made. However, there are important drawbacks, such that far-IR selection of DSFGs in wide fields are restricted only to sources from the brightest-end of the luminosity function. Due to the lack of information from shorter wavelengths, some vital properties of DSFGs, such as stellar mass and AGN-fraction remain unconstrained. In this talk, I will present how to benefit from rich panchromatic data available in deep fields and apply state-of-the art SED modelling techniques in order to unveil the nature of fainter DSFGs. I will discuss how the dust-to-stellar properties of distant sources can be used as a powerful diagnostics tool of their star-formation activity, and refer the status of existing tensions with different galaxy formation models.
