Nature of the cool component in the cD Cluster AWM7

AWM7 is the 2nd brightest poor cluster of galaxies (with kT \\le 4 keV) in thesky next to the Centaurus cluster. Based on the spatially resolved spectra ofthe central cool component, we can unambiguously determine the origin of thecool component and look into its evolution process in the cD type clusters. Thecool component of AWM7 is extended and is probably in an early stage ofevolution, placing this cluster an important target for the systematic study ofthe coolcomponent evolution. The proposed 30 ks observation will also enable usto examine nonuniformity in the spatial distribution of metals, and further toestimate the cusp structure of the gravitational potential which confines thehotcomponent gas. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
