Around ZwCl0823.2+0425, several dark matter halos are found via the Local Cluster Substructure Survey (LoCuSS), which suggests that those halos constitute large-scale structure filaments. We observed a region around the cluster ZwCl0823.2+0425 (z = 0.2248) with Suzaku. ZwCl0823.2+0425 itself and the halo in the north of it are clearly bright in X-ray. According to the SDSS spectroscopic data, the north and northeast halos are at the redshift of z = 0.472, and the northwest one is at that of z = 0.2248. Therefore, it is clear that two large-scale filaments overlap in this region. In the northeast halo area, where the lensing signal is relatively weak, very faint X-ray excess is detected. On the other hand, in the northwest and southeast small halo area, which have the stronger weak lensing signal than the northeast halo area, little X-ray excess is detected. Such a diversity of X-ray properties suggests a variety of the concentration degree of baryon and baryon fraction itself. We investigate L(sub x)-T and M-T relations for ZwCl0823.2+0425 and the other sub halos. The obtained L(sub x)-T relation does not agree with the former typical results, and the M-T relation is slightly deviated from the self-similar model (3.3sigma), though any systematic errors of the background are not considered at present. |
