Description
We present precise Sunyaev-Zeldovich (SZ) effect measurements in the
direction of 62 nearby galaxy clusters (z < 0.5) detected at high
signal-to-noise in the first Planck all-sky data set. The sample spans
approximately a decade in total mass, 2 × 1014
M&sun; < M500 < 2 × 1015
M&sun;, where M500 is the mass corresponding to a
total density contrast of 500. Combining these high quality Planck
measurements with deep XMM-Newton X-ray data, we investigate the
relations between DA2 Y500, the
integrated Compton parameter due to the SZ effect, and the X-ray-derived
gas mass Mg,500, temperature TX, luminosity
LX,500, SZ signal analogue YX,500 =
Mg,500 × TX, and total mass M500.
After correction for the effect of selection bias on the scaling
relations, we find results that are in excellent agreement with both
X-ray predictions and recently-published ground-based data derived from
smaller samples. The present data yield an exceptionally robust,
high-quality local reference, and illustrate Planck's unique
capabilities for all-sky statistical studies of galaxy clusters.
