Constraints on the normal branch of DGP gravity from SPT galaxy clusters with DES and HST weak-lensing mass calibration and from Planck PR4 CMB anisotropies
S. M. L. Vogt, S. Bocquet, C. T. Davies +49
We present constraints on the normal branch of the Dvali-Gabadadze-Porrati (nDGP) braneworld gravity model from the abundance of massive galaxy clusters. On scales below the nDGP c…
Constraints on 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 gravity model using a sample of 1,005 galaxy clusters in the redshift range that have been selected through the thermal Sunyaev-Z…
Constraining gravity using future galaxy cluster abundance and weak-lensing mass calibration datasets
Sophie M. L. Vogt, Sebastian Bocquet, Christopher T. Davies +2
We present forecasts for constraints on the Hu \& Sawicki modified gravity model using realistic mock data representative of future cluster and weak lensing surveys. We crea…
Probing interacting dark sector models with future weak lensing-informed galaxy cluster abundance constraints from SPT-3G and CMB-S4
Asmaa Mazoun, Sebastian Bocquet, Mathias Garny +3
We forecast the sensitivity of ongoing and future galaxy cluster abundance measurements to detect deviations from the cold dark matter (CDM) paradigm. Concretely, we consider a cla…
