ACT-pol deep field. X+SZ+WL HSC clusters X+WL eROSITA (HSC survey region= 2-4ksec = 4-8ksec of XMM) is too shallow for cluster sciences Astro-H/SXS = very bright clusters full sky XMM (deep)+ HSC WL analysis at early phase of eROSITA stacked X+WL analysis in eROSITA/HSC era from Peter Predehl’s file (X-ray Universe 2014) Definition of X-ray luminous clusters is important for both Astro-H and XMM/eROSITA 24 MCXC clusters (we are preparing XMM proposal) MCXC clusters SXS : direct measurement of gas motions (e.g. turbulence,bulk motions) is one of outstanding problems in both cluster physics and cluster cosmology. ? @ central regions non-thermal pressure Astro-H/SXS WL mass HSC hydrostatic equilibrium mass (X-ray) XMM/Chandra Targets : 1 Cool-core of very luminous clusters 2 Merging/Cold-front clusters 3 Systematic Study (e.g. MCXC clusters in HSC survey region) SXS : cool-core in X-ray luminous clusters Hydra A SXS FoV ~3x3 arcmin^2 * gravity wave dominated ?

SXS Hydra A : WL+BCG Kinematics (Okabe+ in prep) z~0.05 figure removed HSC(+Kinematics +SL) vs AstroH+XMM/Chandra would be powerful. SXS : cold front cluster (e.g. A2034) cold front Cold front (=contact discontinuity ) is formed by a moving dark matter clump. moving gas Okabe+Umetsu08 z~0.09 Waked velocity field is calculated by linear perturbation theory for a moving point source (Mwl) in the gas. SXI : 1 spatial resolution ~ 1 arcmin 2 powerful to detect faint X-ray emission 3 similar to Suzaku’s instrument.

Correlation between the outskirts temperature (or density) and surrounding large scale structure is found in a few clusters. Kawaharada,Okabe+10 kBT Galaxy distribution (SDSS) could be replaced by HSC data Photometric data is important to determine X-ray pointings. Joint Suzaku X-ray + Subaru WL analysis Entropy profile normalized by WL M200c and r200c •developed a simultaneous fitting method considering Entropy flattens mass-observable at > ~ 0.5 r500 scaling relation and radial profile. •Thermalization mechanism over the entire cluster region is controlled by the gravity. shock heating model self-similar profile Okabe+14 •Heating efficiency in cluster outskirts needs to be modified from the standard law. Joint fit to Density and Temperature Profiles slightly shallower steeply drops Considered error covariance matrix and intrinsic scatter. Caused by the steeping T profile, rather than the flattening n profile. Systematic study of SXI + HSC WL+photometric data on 24 MCXC clusters should be conducted. 1: hard X-ray imager HXI : 2: one-order lower background Targets: radio halo/relic clusters to detect inverse Compton X-ray emission of Cosmic-ray electrons and constrain magnetic strength.
