Disentangling modified gravity from a dark force with gravitational redshift
Sveva Castello, Zhuangfei Wang, Lawrence Dam +2
The standard approach to test for deviations from general relativity on cosmological scales is to combine measurements of the growth rate of structure with gravitational lensing. I…

Extending MGCAMB tests of gravity to nonlinear scales
Zhuangfei Wang, Daniela Saadeh, Kazuya Koyama +4
Modified Growth with {\tt CAMB} ({\tt MGCAMB}) is a patch for the Einstein-Boltzmann solver {\tt CAMB} for cosmological tests of gravity. Until now, {\tt MGCAMB} was limited to sca…
