Query: On the intermediate-redshift central stellar mass-halo mass relation,
  and implications for the evolution of the most massive galaxies since z~1   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 debated. Several recent
works support a relation in the local Universe steeper than previously thought.
Based on the comparisons with a variety of data on massive central galaxies, we
show that this steepening holds up to z~1, for stellar masses Mstar>2e11 Msun.
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
BOSS 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
Mstar>3e11 Msun, 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.
