Testing chameleon gravity with the Coma cluster
Ayumu Terukina, Lucas Lombriser, Kazuhiro Yamamoto +3
We propose a novel method to test the gravitational interactions in the outskirts of galaxy clusters. When gravity is modified, this is typically accompanied by the introduction of…
Halo modelling in chameleon theories
Lucas Lombriser, Kazuya Koyama, Baojiu Li
We analyse modelling techniques for the large-scale structure formed in scalar-tensor theories of constant Brans-Dicke parameter which match the concordance model background expans…
Modeling halo mass functions in chameleon f(R) gravity
Lucas Lombriser, Baojiu Li, Kazuya Koyama +1
On cosmological scales, observations of the cluster abundance currently place the strongest constraints on f(R) gravity. These constraints lie in the large-field limit, where the m…
Relativistic effects in galaxy clustering in a parametrized post-Friedmann universe
Lucas Lombriser, Jaiyul Yoo, Kazuya Koyama
We explore the signatures of quintessence and modified gravity theories in the relativistic description of galaxy clustering within a parametrized post-Friedmann framework. For thi…
