Weak Lensing Mass Determination of Eight X-ray Selected Galaxy Clusters from the 400d Survey
(2011-01-19)
Evolution in the mass function of galaxy clusters sensitively traces both the expansion history of the Universe and cosmological structure formation. Hence, measuring the number density of galaxy clusters as a function of ...
Cosmic Shear and the Intrinsic Alignment of Galaxies
(2010-11-12)
Cosmology has recently entered an era of increasingly rich observational data sets, all being in agreement with a cosmological standard model that features only a small number of free parameters. One of the most powerful ...
Forecasts for Galaxy Cluster Observations and Cosmological Implications from the eROSITA All-Sky Survey
(2016-04-19)
One of the most commonly asked questions in astrophysics today refers to the nature of dark energy. The characteristics of this parameter are imprinted in the large-scale structure of matter and accordingly also in the ......
