Abstract

We propose a new method to model cluster scaling relations in modified gravity. Using a suite of nonradiative hydrodynamical simulations, we show that the scaling relations of accumulated gas quantities, such as the Sunyaev-Zel’dovich effect (Compton-y parameter) and the x-ray Compton-y parameter, can be accurately predicted using the known results in the ΛCDM model with a precision of ∼3%. This method provides a reliable way to analyze the gas physics in modified gravity using the less demanding and much more efficient pure cold dark matter simulations. Our results therefore have important theoretical and practical implications in constraining gravity using cluster surveys.
