Quasar luminosity functions at z = 0.5, 1.0, 2.0, 3.0 for the Quiet (blue) and Boosted model (red) run in the Millennium merger trees (i.e. L-Galaxies + MS). The error bars correspond to the Poissonian error. The results are compared with the observations of Hopkins et al. (2007) (triangles), Aird et al. (2015) (squares) and Shen et al. (2020) (circles). The lower panel represents the ratio between the model and the data points.
