The relation between the central galaxy properties and the dynamical state of the cluster
Abstract
In X-ray analysis, a variety of cooling criteria have been proposed to separate cool-core clusters and non-cool core clusters, in which classification attempts are generally based on core properties because cluster centres are more easily accessible. These indicators are typically based on a central temperature drop (e.g., Burns et al. 2008), a central cooling time shorter than the Hubble time (e.g., Bauer et al. 2005), or a significant mass deposition (Chen et al. 2007).
The optical analysis of the central galaxy was performed using the Starlight spectral synthesis code (Cid Fernandes et al., 2005). For the X-ray analysis, we use data from the XMM-Newton and Chandra satellites. As preliminary results, we verified a first indication of the relation between the global dynamical state of the cluster and the position of the central galaxy of the cluster in two diagnostic diagrams, namely the BPT (Baldwin et al., 1981) and WHAN (Cid Fernandes 2011).
