Cross correlations with CMB secondaries: constraining cosmological parameters and cluster astrophysics
Nick Battaglia
Princeton
High resolution CMB experiments, such as ACT, SPT, and the Planck satellite
are making precision measurements of the secondary anisotropies caused by
the thermal Sunyaev Zel'dovich (tSZ) effect from galaxy clusters. However,
our ability to obtain cosmological information from this tSZ signal is
limited by our theoretical understanding of the baryons in clusters and
groups. I will discuss how cross-correlation methods are providing new
windows into the messy "astrophysics" of the intracluster medium and the
potential for these methods to constrain various cosmological parameters.
