Cosmology Seminar: Jochen Weller
Jochen Weller is a professor at the Ludwigs-Maximilians-Universität (LMU) in Munich.
Cosmology with Clusters of Galaxies
I will explain how the redshift and mass distribution of galaxy cluster can be exploited to constrain cosmological models. I will then present constraints from cluster cosmology from observations with the Planck satellite and from optical cluster finding in the Sloan Digital Sky Survey. I will put some particular emphasis on the complementary information from the large scale clustering of galaxy clusters. Finally I will discuss the first measurement of the cross correlation of galaxy clusters with galaxies.
