We carried out observations of the central and 20 east offset regions of the cluster of galaxies Abell 1060 with Suzaku. Spatially resolved X-ray spectral analysis has revealed temperature and abundance profiles of Abell 1060 out to 27 ~ 380; /h_70 kpc, which corresponded to ~ 0.25; r_180. Temperature decrease of the intra cluster medium from 3.4 keV at the center to 2.2 keV in the outskirt region are clearly observed. Abundances of Si, S and Fe also decrease by more than 50% from the center to the outer, while Mg shows fairly constant abundance distribution at ~ 0.7 solar within r < 17. O shows lower abundance of ~ 0.3 solar in the central region (r~ 6), and indicates a similar feature with Mg, however it is sensitive to the estimated contribution of the Galactic components of kT_1 ~ 0.15 keV and kT_2 ~ 0.7 keV in the outer annuli (r ~ 13). Systematic effects due to the point spread function tails, contamination on the XIS filters, instrumental background, cosmic and/or Galactic X-ray background, and the assumed solar abundance tables are carefully examined. Results on temperature and abundances of Si, S, and Fe are consistent with those derived by XMM-Newton at r < 13. Formation and metal enrichment process of the cluster are discussed based on the present results.
We present results of 120 ks observation of a compact group of galaxies HCG~62 ($z=0.0145$) with Suzaku XIS and HXD-PIN@. The XIS spectra for four annular regions were fitted with two temperature {it vapec} model with variable abundance, combined wit
We present results from the XMM-Newton observation of the non-cooling flow cluster A1060. Large effective area of XMM-Newton enables us to investigate the nature of this cluster in unprecedented detail. From the observed surface brightness distributi
We present an X-ray spectral analysis of the nearby double radio relic merging cluster Abell 3376 ($z$ = 0.046), observed with the $Suzaku$ XIS instrument. These deep ($sim$360 ks) observations cover the entire double relic region in the outskirts of
We carried out 3 observations of the cluster of galaxies AWM 7, for the central region and 20-east and 20-west offset regions, with Suzaku. Temperature and abundance profiles are measured out to 27~ 570 /h_70 kpc, which corresponded to ~0.35 r_180. T
The results from Suzaku XIS observations of the relaxed cluster of galaxies Abell2052 are presented. Offset pointing data are used to estimate the Galactic foreground emission in the direction to the cluster. Significant soft X-ray excess emission ab
