Galaxy-galaxy lensing data: gravity challenges General Relativity
Qingqing Wang, Xin Ren, Bo Wang +3
We use galaxy-galaxy lensing data to test General Relativity and gravity at galaxies scales. We consider an exact spherically symmetric solution of theory which is ob…

The effective field theory approach to the strong coupling issue in gravity
Yu-Min Hu, Yaqi Zhao, Xin Ren +3
We investigate the scalar perturbations and the possible strong coupling issues of around a cosmological background, applying the effective field theory (EFT) approach. We r…

Stochastic gravitational wave background from the collisions of dark matter halos
Qiming Yan, Xin Ren, Yaqi Zhao +1
We investigate the effect of the dark matter (DM) halos collisions, namely collisions of galaxies and galaxy clusters, through gravitational bremsstrahlung, on the stochastic gravi…
