Description
Cross-correlation/stacking analyses of Sunyaev-Zeldovich observations and galaxy surveys offer a promising method for studying properties of the gas reservoirs surrounding galaxies and the astrophysics that govern their evolution. These statistical studies can be used to constrain models and simulations through a detailed forward model, but the implementation and systematics of constructing a predicted signal can introduce significant sources of error into the results. We discuss the effects of survey modeling such as Halo Occupancy Distributions in the forward model and its relevance to the current discrepancy between simulations and observations, and present some early results using new data and simulations with our improved pipeline.
