This cluster, located behind the Milky way, was recently found to be a nearby, X-ray bright and very rich cluster. Pointed observations onto the central region of the cluster gave a gas temperature of $sim7$ keV and a metallicity of about 0.2 solar. An offset pointing to a substructure elongated to south-east of the cluster center gave a significantly lower temperature of $sim 5$ keV. The 2--10 keV luminosity within a radius of 40’ (1.1 Mpc) is estimated to be $3.7 imes 10^{44} erg/s$. The X-ray data imply a cluster mass of about $4 imes 10^{14}$ $M_odot$ within 40’. | | Source: | arXiv, astro-ph/9802319 | | Services: | Forum | Review | PDF | Favorites | |
