Query: LoCuSS: Scaling relations between galaxy cluster mass, gas, and stellar
  content   We present a simultaneous analysis of galaxy cluster scaling relations
between weak-lensing mass and multiple cluster observables, across a wide range
of wavelengths, that probe both gas and stellar content. Our new hierarchical
Bayesian model simultaneously considers the selection variable alongside all
other observables in order to explicitly model intrinsic property covariance
and account for selection effects. We apply this method to a sample of 41
clusters at $0.15<z<0.30$, with a well-defined selection criteria based on RASS
X-ray luminosity, and observations from Chandra / XMM, SZA, Planck, UKIRT, SDSS
and Subaru. These clusters have well-constrained weak-lensing mass measurements
based on Subaru / Suprime-Cam observations, which serve as the reference masses
in our model. We present 30 scaling relation parameters for 10 properties. All
relations probing the intracluster gas are slightly shallower than self-similar
predictions, in moderate tension with prior measurements, and the stellar
fraction decreases with mass. K-band luminosity has the lowest intrinsic
scatter with a 95th percentile of 0.16, while the lowest scatter gas probe is
gas mass with a fractional intrinsic scatter of $0.16 \pm 0.03$. We find no
distinction between the core-excised X-ray or high-resolution
Sunyaev-Zel'dovich relations of clusters of different central entropy, but find
with modest significance that higher entropy clusters have higher stellar
fractions than their lower entropy counterparts. We also report posterior mass
estimates from our likelihood model.
