SUMMARY:Workshop / Seminar:Special Cosmology Seminar | Galaxy Cluster Scaling Relations with the Magneticum Simulation
DESCRIPTION:Galaxy clusters are one of the most powerful cosmological tool. Their abundance as a function of cluster mass is sensitive to both the expansion history and the history of structure formation in the Universe. Various cluster observables such as X-ray luminosity\, temperature and Sunyaev- Zel’dovich (SZ) effect have been shown to scale with cluster mass\, therefore\, can be used as a proxy of total cluster mass.\n\nWe use Magneticum simulation setup to explore the cosmology dependence of galaxy cluster scaling relations which otherwise cannot be tested by observations. We run the same simulation set-up in fifteen different cosmological environments. Our simple\, cosmology dependent mass-observable scaling relation parametrisation can be used to forecast the degeneracies between the amplitude of the scaling relation and the cosmological parameters as well as to explore the combination of potential probes to break these degeneracies.
