Oral Presentation Clusters and Cosmology I


Prof. Daisuke Nagai (Yale University)


eROSITA mission will soon produce an unprecedented number of galaxy clusters, which in turn should help improve X-ray based cosmological measurements. However, in order to use the eROSITA data for precision cosmology, we must improve our understanding of the physics of X-ray emitting intracluster medium (ICM) and develop techniques to control associated systematic uncertainties in cluster mass estimates. In this work, I will discuss (1) recent advances in our understanding of ICM physics and cluster mass estimation based on hydrodynamical simulations and X-ray and microwave observations and (2) strategies to improve both cluster astrophysics and cosmology using the forthcoming eROSITA data.
