Contribution

It provides the first detailed temperature maps for these clusters, illustrating their diverse dynamical states and contributing to understanding cluster formation and evolution.

Findings

Temperature variations indicate different dynamical states.

Evidence of mergers in some clusters.

Insights into cluster formation history.

Abstract

We have analyzed XMM-Newton archive data for five clusters of galaxies (redshifts 0.223 to 0.313) covering a wide range of dynamical states, from relaxed objects to clusters undergoing several mergers. We present here temperature maps of the X-ray gas together with a preliminary interpretation of the formation history of these clusters.
