The WIRCAM Deep Infrared Cluster Survey I: Groups and Clusters at z ~1.1


Our observations suggest that there are perhaps too few clusters at z > 1 compared to predictions using WMAP-7 cosmology. However, the current level of statistical and systematic uncertainties prevent drawing a more secure conclusion. Ultimately, cluster number counts can provide a complimentary and independent method for constraining the cosmological model.

Tough paper, hedgy but intriguing conclusion.
