Large-Scale Structure and X-ray Clusters of Galaxies
Abstract
Description
I review recent progress in the study of the large-scale structure of the Universe through the distribution of clusters of galaxies, concentrating on new results using X-ray selected samples. After discussing the importance of understanding the properties of the tracers used to map structure and their relation to the underlying mass, I elaborate on the advantages and disadvantages of clusters of galaxies to this end. I then present the most recent estimates of the power spectrum and correlation function of X-ray clusters in the local (z~0.2) Universe, and their implications for cosmological models. Finally, I briefly summarize most recent results from deep X-ray surveys as probes of the evolution of structure and highlight current ongoing observational efforts in this field.
