Abstract
Recent X-ray observations have been showing that the old vision of
clusters as peacefully relaxed structures is in most cases absolutely
wrong. Coupled with optical and radio observations, these X-ray data
show evidence for violent mechanisms. Results based on XMM-Newton gas
temperature maps for four clusters will be presented here.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link containsarticle metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means:
- if your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages,
- you can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library,
- you can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
