  • Matching the number counts of high-z sub-millimetre-selected galaxies (SMGs) has been a long standing problem for galaxy formation models. In this paper, we use 3D dust radiative transfer to model the sub-mm emission from galaxies in the Simba cosmological hydrodynamic simulations, and compare predictions to the latest singledish observational constraints on the abundance of 850 μm-selected sources. We find unprecedented agreement with the integrated 850 μm luminosity function, along with good… CONTINUE READING
