Forecasts for Galaxy Cluster Observations and Cosmological Implications from the eROSITA All-Sky Survey
Borm, Katharina (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 ... -
Search for solar chameleons with an InGrid based X-ray detector at the CAST experiment
Krieger, Christoph (2018-08-15)Chameleons are particles with a density dependent effective mass and couplings to matter as well as photons. They are introduced in modifications to General Relativity involving scalar fields and aiming at explaining Dark ... -
Weak Lensing Mass Determination of Eight X-ray Selected Galaxy Clusters from the 400d Survey
Israel, Holger (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 ...
