Constraints on the correlation between QSO luminosity and host halo mass from high-redshift quasar clustering
Recent measurements of high-redshift quasar (QSO) clustering from the Sloan Digital Sky Survey indicate that QSOs at z∼ 4 have a bias 〈b〉≃ 14. We find that this extremely high clustering amplitude, combined with the corresponding space density, constrains the dispersion in the L–Mh relation to be less than 50 …
