Smith X - ray Cluster Large Scale Structure and Cosmology
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 past surveys, we present the scientific motivations of the XMM Large Scale Structure survey. We further illustrate how such a survey can help constrain the nature of the dark energy as well as cluster scaling law evolu...
متن کاملThe XMM Large Scale Structure survey: The X-ray pipeline and survey selection function
We present the X-ray pipeline developed for the purpose of the cluster search in the XMM-LSS survey. It is based on a two-stage procedure via a dedicated handling of the Poisson nature of the signal: (1) source detection on multi-resolution wavelet filtered images; (2) source analysis by means of a maximum likelihood fit to the photon images. The source detection efficiency and characterisation...
متن کاملThe Bright SHARC Survey : The X – ray Cluster Luminosity Function
We present here initial results on the X–ray Cluster Luminosity Function (XCLF) from the Bright SHARC sample of distant X–ray clusters of galaxies. This sample is 97% complete in its optical identifications and contains 12 X–ray luminous clusters in the redshift range 0.3 ≤ z ≤ 0.83 (median z = 0.42) and 1.1 ≤ Lx ≤ 8.5 × 10 erg s−1 [0.5–2.0 keV]. We present a preliminary selection function for ...
متن کاملThe XMM Cluster Survey: X-ray analysis methodology
The XMM Cluster Survey (XCS) is a serendipitous search for galaxy clusters using all publicly available data in theXMM–NewtonScience Archive. Its main aims are to measure cosmological parameters and trace the evolution of X-ray scaling relations. In this paper we describe the data processing methodology applied to the 5776 XMM observations used to construct the current XCS source catalogue. A t...
