Red-sequence cluster finding in the Millennium Simulation
Red-sequence cluster finding in the Millennium Simulation
We investigate halo mass selection properties of red-sequence cluster finders using galaxy populations of the Millennium Simulation (MS). A clear red sequence exists for MS galaxies in massive haloes at redshifts z < 1, and we use this knowledge to inform a cluster-finding algorithm applied to 500 h−1 Mpc projections …
