HSC-XXL : Baryon budget of the 136 XXL Groups and Clusters
  We present our determination of the baryon budget for an X-ray-selected XXL
sample of 136 galaxy groups and clusters spanning nearly two orders of
magnitude in mass ($M_{500}\sim 10^{13}-10^{15}M_\odot$) and the redshift range
$0< z < 1$. Our joint analysis is based on the combination of HSC-SSP
weak-lensing mass measurements, XXL X-ray gas mass measurements, and HSC and
SDSS multiband photometry. We carry out a Bayesian analysis of multivariate
mass-scaling relations of gas mass, galaxy stellar mass, stellar mass of
brightest cluster galaxies (BCGs), and soft-band X-ray luminosity, by taking
into account the intrinsic covariance between cluster properties, selection
effect, weak-lensing mass calibration, and observational error covariance
matrix. The mass-dependent slope of the gas mass--total mass ($M_{500}$)
relation is found to be $1.29_{-0.10}^{+0.16}$, which is steeper than the
self-similar prediction of unity, whereas the slope of the stellar mass--total
mass relation is shallower than unity, $0.85_{-0.09}^{+0.12}$. The BCG stellar
mass weakly depends on cluster mass with a slope of $0.49_{-0.10}^{+0.11}$. The
baryon, gas mass, and stellar mass fractions as a function of $M_{500}$ agree
with the results from numerical simulations and previous observations. We
successfully constrain the full intrinsic covariance of the baryonic contents.
The BCG stellar mass shows the larger intrinsic scatter at a given halo total
mass, followed in order by stellar mass and gas mass. We find a significant
positive intrinsic correlation coefficient between total (and satellite)
stellar mass and BCG stellar mass and no evidence for intrinsic correlation
between gas mass and stellar mass.
  All the baryonic components show no redshift evolution.
