Constraining Cosmology with High Convergence Regions in Weak Lensing Surveys
TL;DR: In this article, the fractional area of hot spots in weak gravitational lensing mass maps which are detected with high significance is used to determine background cosmological parameters, which are comparable to those from the redshift distribution of galaxy cluster abundances.

TL;DR: The amount and nature of dark energy can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the redshift range 0

Breaking Cosmological Degeneracies in Galaxy Cluster Surveys with a Physical Model of Cluster Structure
TL;DR: In this article, the authors examined an alternative approach to self-calibration, in which a parametrized ab-initio physical model is used to compute theoretical mass-observable relations from the cluster structure.
Is modified gravity required by observations? An empirical consistency test of dark energy models
TL;DR: In this paper, the authors apply the technique of parameter splitting to existing cosmological data sets, to check for a generic failure of dark energy models, and they find that the Dvali-Gabadadze-Porrati model is consistent with current data.
