Constraints on $f(R)$ gravity from tSZE-selected SPT galaxy clusters and weak lensing mass calibration from DES and HST

S. M. L. Vogt, S. Bocquet, C. T. Davies +52

We present constraints on the $f(R)$ gravity model using a sample of 1,005 galaxy clusters in the redshift range $0.25-1.78$ that have been selected through the thermal Sunyaev-Z…
