A serendipitous survey for galaxy clusters by the XMM-Newton Survey Science Center
A. D. Schwope, G. Lamer, D. Burke +5
We describe the initial results of a programme to detect and identify extended X-ray sources found serendipitously in XMM-Newton observations. We have analysed 186 EPIC-PN images a…
