A quadruply imaged quasar with an optical Einstein ring candidate: 1RXS J113155.4-123155
D. Sluse, J. Surdej, J. -F. Claeskens +6
We report the discovery of a new quadruply imaged quasar surrounded by an optical Einstein ring candidate. Spectra of the different components of 1RXS J113155.4-123155 reveal a sou…

The XMM-LSS Survey. First high redshift galaxy clusters: relaxed and collapsing systems
I. Valtchanov, M. Pierre, J. Willis +11
We present five newly found galaxy clusters at z>0.6 from the XMM Large-Scale Structure Survey (XMM-LSS). All five objects are extended X-ray sources in the XMM images. For three o…

The XMM-LSS survey. Survey design and first results
M. Pierre, I. Valtchanov, B. Altieri +36
We have designed a medium deep large area X-ray survey with XMM - the XMM Large Scale Structure survey, XMM-LSS - with the scope of extending the cosmological tests attempted using…
