Colour-detected clusters in the XMM Large Scale Structure Survey
S. Andreon, J. Willis, H. Quintana +3
We present first results on the use of a colour space filter for detecting galaxy clusters at cosmological redshifts in the XMM Large Scale Structure Survey. All clusters studied,…
X-ray Cluster Large Scale Structure and Cosmology
Marguerite Pierre
We outline main arguments in favor of cosmological X-ray surveys of galaxy clusters. We summarize recent advances in our understanding of cluster physics. After a short review of p…
The XMM Large Scale Structure Survey: Scientific Motivation and First Observations
M. Pierre, I. Valtchanov, A. Refregier
Thanks to its unrivalled sensitivity and large field of view, XMM potentially occupies a leading position as a survey instrument. We present cosmological arguments in favour of a m…
The XMM-LSS Survey: Mapping hot, luminous, obscured and dark material out to z~1-2
Marguerite Pierre
We review the unique cosmological implications of the XMM-LSS survey in association with its multi-WL follow-up: (1) Large Scale Structures traced by X-ray clusters and AGNs, optic…
Probing the gravitational potential of a nearby lensing cluster Abell 2104
H. Liang, L. Lemonon, I. Valtchanov +2
The cluster Abell 2104 is one of the lowest redshift clusters (z=0.153) known to have a gravitational lensing arc. We present detailed analysis of the cluster properties such as th…
An XMM pre-view of the cosmic network: galaxy groups and filaments
M. Pierre, G. Bryan, R. Gastaud
A large fraction of the baryons today are predicted to be in hot, filamentary gas, which has yet to be detected. In this paper, we use numerical simulations of dark matter and gas…
