Description

We present two mock redshift surveys of the dusty star-forming galaxy population based on N-body simulations that reproduce the observed surface density of galaxies at 0.5 to 2.0mm. The largest simulated area (100 sq. deg) allows us to identify gravitationally bound systems, trace their assembly histories, and quantify the redshift evolution of their galaxy content and size. We find a strong evolution in the fractional contribution of different star-forming galaxy populations within cluster progenitors. Luminous infrared galaxies are ∼20–40 per cent of the cluster/protocluster members, with the more luminous systems concentrating further into the centers at z > 1.5. Based on these mock catalogs we provide observational predictions for TolTEC on the 50m LMT and AtLAST.
