We use the conditional luminosity function �(L|M)dL, which gives the number of galaxies with luminosities in the range L±dL/2 that reside in a halo of mass M, to link the distribution of galaxies to that of dark matter haloes. Starting from the number density of dark matter haloes predicted by current models of structure formation, we seek the form of �(L|M) that reproduces the galaxy luminosity function and the luminosity dependence of the galaxy clustering strength. We test the models of �(L|M) by comparing the resulting mass-to-light ratios with constraints from the Tully-Fisher (TF) relation and from galaxy clusters. A comparison between model predictions and current observations yields a number of stringent constraints on both galaxy formation and cosmology. In particular, this method can break the degeneracy between 0 and the power-spectrum normalization �8, inherent in current weak-lensing and cluster

THE LUMINOSITY AND STELLAR MASS FUNCTIONS (2008, methodology): “A roughly constant dispersion in the lognormal distribution of luminosity (or stellar mass) for central galaxies has already been predicted by Yang et al. (2003), Cooray (2006) and Cacciato et al. (2008) from the clustering and abundances of galaxies.”

HALO OCCUPATION DISTRIBUTION MODELING OF CLUSTERING OF LUMINOUS RED GALAXIES (2008, methodology): “Through fitting rest-frame B-band galaxy luminosity functions at different redshifts using a CLF approach, Cooray (2005) finds that the data are compatible with a halo-mass-dependent central galaxy luminosity evolution, with the high-mass slope p increasing with redshift.”

The DEEP2 galaxy redshift survey: evolution of the colour–density relation at 0.4 < z < 1.35 (2006, methodology): “The luminosities of galaxies are then assigned according to the conditional luminosity function (CLF) formalism introduced by Yang et al.

The mass function and average mass-loss rate of dark matter subhaloes (2004, background): “This will prove especially fruitful in combination with the conditional luminosity function formalism developed by Yang et al.

Towards a concordant model of halo occupation statistics (2006, methodology): “Motivated by reionization considerations (see Yang et al. 2003 for details), we adopt Mmin = 109 h−1 M throughout.”
ANGULAR MOMENTUM AND GALAXY FORMATION REVISITED (2012, background): “This is because the observed luminosity function of galaxies has a dramatically different shape from the predicted mass function of DM halos (e.g., White & Rees 1978; White & Frenk 1991; Marinoni & Hudson 2002; Yang et al. 2003; Moster et al. 2010).”
