Constraints on f (R) gravity from thermal-Sunyaev-Zel'dovich-effect-selected SPT galaxy clusters and weak lensing mass calibration from des and HST

Abstract

We present constraints on the f(R) gravity model using a sample of 1005 galaxy clusters in the redshift range 0.25-1.78 that have been selected through the thermal Sunyaev-Zel'dovich effect from South Pole Telescope data and subjected to optical and near-infrared confirmation with the multicomponent matched filter algorithm. We employ weak gravitational lensing mass calibration from the Dark Energy Survey Year 3 data for 688 clusters at z<0.95 and from the Hubble Space Telescope for 39 clusters with 0.6 3×1014M⊙.
