Title A complete sample of massive MaxBCG clusters for scaling relations

Description Great progress on galaxy clusters has been made in the last several years with
SZ and optical surveys. Some new puzzles also emerged and one of them is the
mismatch between the stacked Planck SZ fluxes and the model expectations for the
MaxBCG clusters. While previous studies regarding this puzzle require the
calibration of the true mass and the standard pressure template, we bypass the
intermediate steps to directly compare the pressure content derived from the
X-ray data with the SZ flux, for massive MaxBCG clusters. This proposal requests
XMM data for 7 clusters to complete a sample of 38 most massive MaxBCG clusters
observed with either XMM or Chandra. The results will shed light on the mismatch
puzzle and constrain the important scaling relations like Y_X - N & Y_X - Y_SZ.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
