Planckearly results. XII. Cluster Sunyaev-Zeldovich optical scaling relations

Abstract: We present the Sunyaev-Zeldovich (SZ) signal-to-richness scaling relation (Y 500 − N 200 ) for the MaxBCG cluster catalogue. Employing a multifrequency matched filter on the Planck sky maps, we measure the SZ signal for each cluster by adapting the filter according to weak-lensing calibrated mass-richness relations (N 200 − M 500 ). We bin our individual measurements and detect the SZ signal down to the lowest richness systems (N 200 = 10) with high significance, achieving a detection of the SZ signal in syste… Show more

“…Figure 13 is a modern incarnation of an old problem. Reference [89] studied the scaling relation between the richness of maxBCG clusters [90] and the SZ signature of those clusters using Planck data. They found both a large amplitude offset, and a large difference in the slope, relative to that predicted using weak-lensing masses.…”

“…Because of their high luminosities, it is now possible to construct large samples of QSOs from wide-field spectroscopic surveys (e.g. Pâris et al 2016), making this subclass of AGN well suited to statistical studies of AGN feedback energetics. Forman et al 2007;and Miley & De Breuck 2008;Fabian 2012 for reviews).…”

“…Fortunately, this is more clear than prior to Planck. We now know from Planck SZ observations [171,173] that the SZ signal scales with mass according to our adopted relation down to much smaller masses in the local universe, leaving as our main uncertainty the presently poor knowledge of its redshift dependence. PRISM will determine this evolution, through its mass measurement capabilities (see below), and constrain cosmology from the observed cluster evolution.…”

“…We will explore the gas content of dark matter halos down to very low masses, a research area pioneered by Planck by stacking SZ measurements based on known objects to detect the signal down below 10 13 solar masses [171,173]. This measurement over such a vast mass range is unique to the SZ effect and a highly valuable constraint on feedback mechanisms at the heart of galaxy formation.…”
