Nature of Point Sources from Aquarius Supercluster
Abstract
We present the results from spatial and spectral study of 30 x-ray point sources from the Aquarius supercluster, one of the highest concentrations of rich clusters in the sky. Archival Chandra and ASCA data are used for understanding the properties of extended hot plasma emissions. X-ray data mainly covers the bright rich clusters: A2534, A2550, A2555 and A2556. All the sources have optical counterparts (except 2 sources). The central bright galaxies are observed to be strong radio emitters. The X-ray spectral properties are studied and compared with Lockman Hole field-galaxies. The enhanced X-ray emission from the sources is explained by ICM galaxy interaction in the high density cluster outskirts.
