Marked correlation function as modified gravity probe
Abstract
For modified gravity models with screening mechanisms, the signal of modified gravity is larger at low density areas. We could add a density weighted mark to galaxy correlation function and increase the signal to noise of modified gravity detection. Based on mock galaxy catalogs from modified gravity simulations, we try different mark functions and parameters to find the best choices for discreminating modified gravity from GR. In this talk I will present our marked correlation funciton results and discuss its advantages and disadvantages.
