A New Measure of Assembly Bias Using the Environment Dependence of the Luminosity Function

A New Measure of Assembly Bias Using the Environment Dependence of the Luminosity Function

Assembly bias is the variation in the clustering of dark matter halos and galaxies that arises from correlations between the halo assembly history and the large-scale environment at fixed halo mass. In this work, we use the cosmological magnetohydrodynamical simulation TNG300 to investigate how asse...
