Tracing dark matter overdensities with dusty star-forming galaxies
It has been suggested that associations of high-redshift dusty star-forming galaxies (DSFGs) may serve as beacons of protoclusters because DSFGs are high-mass galaxies undergoing rapid assembly. We investigate this possibility using the Bolshoi cosmological N-body simulation and a model for populati...
