Observing Galaxy Clusters with eROSITA: Simulations
Presenter: Johannes Hölzl
The eROSITA instrument on board of the spacecraft Spectrum-Roentgen-Gamma, which will be launched in 2013, will conduct an All Sky Survey in X-rays. A main objective of the survey is the observation of galaxy clusters to constrain the cosmological parameters and to gain further knowledge of dark matter and dark energy. The whole survey will be simulated before launch. As an input for this simulation we developed a Monte-Carlo code generating a mock catalogue of galaxy clusters. The clusters are distributed according to the mass function by Tinker et al. (2008). The code generates the celestial coordinates as well as cluster mass and redshift, from these the observables flux and angular diameter are derived.
