Sunyaev-Zeldovich cluster counts as a probe of intra-supercluster gas

Research output: Contribution to journalArticlepeer-review


X-ray background surveys indicate the likely presence of diffuse warm gas in the local super cluster (LSC), in accord with expectations from hydrodynamical simulations. We assess several other manifestations of warm LSC gas; these include anisotropy in the spatial pattern of cluster Sunyaev-Zeldovich (S-Z) counts, its impact on the cosmic microwave background temperature power spectrum at the lowest multipoles, and implications on measurements of the S-Z effect in and around the Virgo cluster.
