Connecting massive galaxies to dark matter haloes in BOSS โ€“ I. Is galaxy colour a stochastic process in high-mass haloes?

We use subhalo abundance matching (SHAM) to model the stellar mass function (SMF) and clustering of the Baryon Oscillation Spectroscopic Survey (BOSS) "CMASS" sample at $z\sim0.5$. We introduce a novel method which accounts for the stellar mass incompleteness of CMASS as a function of redshift, and produce CMASS mock catalogs โ€ฆ
