Improved constraints on dark energy from Chandra X-ray observations of the largest relaxed galaxy clusters

TL;DR: In this paper, Chandra measurements of the X-ray gas mass fraction (fgas )i n 42 hot (kT > 5 keV), Xray luminous, dynamically relaxed galaxy clusters spanning the redshift range 0.05 < z < 1.

TL;DR: In this article, Chandra measurements of the X-ray gas mass fraction (fgas) in 42 hot (kT>5keV) galaxy clusters spanning the redshift range 0.05
Journal ArticleDOI

The Observed Growth of Massive Galaxy Clusters I: Statistical Methods and Cosmological Constraints

TL;DR: In this paper, the authors derive simultaneous constraints on cosmological parameters and X-ray scaling relations using observations of the growth of massive, Xray flux-selected galaxy clusters.
Journal ArticleDOI

The Observed Growth of Massive Galaxy Clusters II: X-ray Scaling Relations

TL;DR: In this article, the authors derived simultaneous constraints on cosmology and X-ray scaling relations using observations of massive, Xray flux-selected galaxy clusters, and provided a new benchmark for comparison with numerical simulations of cluster formation and evolution.

The XXL Survey - I. Scientific motivations − XMM-Newton observing plan − Follow-up observations and simulation programme

Marguerite Pierre, +96 more
TL;DR: The XXL-XMM survey as discussed by the authors provides constraints on the dark energy equation of state from the space-time distribution of clusters of galaxies and serves as a pathfinder for future, wide-area X-ray missions.
