The stellar mass-halo mass relation is a key constraint in all semi-analytic, numerical, and semi-empirical models of galaxy formation and evolution. However, its exact shape and redshift dependence remain under debate. Several recent works support a relation in the local universe steeper than previously thought. Based on comparisons with a variety of data on massive central galaxies, we show that this steepening holds up to z ~ 1 for stellar masses M sub(star) > ~ 2 x 10 super(11) M sub(middot in circle). Specifically, we find significant evidence for a high-mass end slope of beta > ~ 0.35-0.70 instead of the usual beta <, ~ 0.20-0.30 reported by a number of previous results. When including the independent constraints from the recent Baryon Oscillation Spectroscopic Survey clustering measurements, the data, independent of any systematic errors in stellar masses, tend to favor a model with a very small scatter (<, ~0.15 dex) in stellar mass at fixed halo mass, in the redshift range z < 0.8 and for M sub(star) > 3 x 10 super(11) M sub(middot in circle), suggesting a close connection between massive galaxies and host halos even at relatively recent epochs. We discuss the implications of our results with respect to the evolution of the most massive galaxies since z ~ 1.
