A general framework for unbiased tests of gravity using galaxy clusters
Myles A. Mitchell
We present a Markov chain Monte Carlo pipeline which can be used for unbiased large-scale tests of gravity using galaxy cluster observations. The pipeline, which currently uses clu…
A general framework to test gravity using galaxy clusters VI: Realistic galaxy formation simulations to study clusters in modified gravity
Myles A. Mitchell, Christian Arnold, Baojiu Li
We present a retuning of the IllustrisTNG baryonic physics model which can be used to run large-box realistic cosmological simulations with a lower resolution. This new model emplo…
A general framework to test gravity using galaxy clusters V: A self-consistent pipeline for unbiased constraints of gravity
Myles A. Mitchell, Christian Arnold, Baojiu Li
We present a Markov chain Monte Carlo pipeline that can be used for robust and unbiased constraints of gravity using galaxy cluster number counts. This pipeline makes use of…
A general framework to test gravity using galaxy clusters IV: Cluster and halo properties in DGP gravity
Myles A. Mitchell, César Hernández-Aguayo, Christian Arnold +1
We study and model the properties of galaxy clusters in the normal-branch Dvali-Gabadadze-Porrati (nDGP) model of gravity, which is representative of a wide class of theories which…
The impact of modified gravity on the Sunyaev-Zel'dovich effect
Myles A. Mitchell, Christian Arnold, César Hernández-Aguayo +1
We study the effects of two popular modified gravity theories, which incorporate very different screening mechanisms, on the angular power spectra of the thermal (tSZ) and kinemati…
A general framework to test gravity using galaxy clusters III: Observable-mass scaling relations in gravity
Myles A. Mitchell, Christian Arnold, Baojiu Li
We test two methods, including one that is newly proposed in this work, for correcting for the effects of chameleon gravity on the scaling relations between the galaxy clust…
