The coming generation of galaxy surveys will provide measurements of galaxy clustering with unprecedented accuracy and data size, which will allow us to test cosmological models at much higher precision than achievable previously. This means that we... Read More about Towards an accurate model of small-scale redshift-space distortions in modified gravity.

Fast full N-body simulations of generic modified gravity: derivative coupling models (2022)
Journal Article
Hernández-Aguayo, C., Ruan, C.-Z., Li, B., Arnold, C., Baugh, C. M., Klypin, A., & Prada, F. (2022). Fast full N-body simulations of generic modified gravity: derivative coupling models.

We present mg-glam, a code developed for the very fast production of full N-body cosmological simulations in modified gravity (MG) models. We describe the implementation, numerical tests and first results of a large suite of cosmological simulations...

Non-linear matter power spectrum without screening dynamics modelling in f(R) gravity (2020)
Journal Article
Ruan, C.-Z., Zhang, T.-J., & Hu, B. (2020). Non-linear matter power spectrum without screening dynamics modelling in f(R) gravity. Monthly Notices of the Royal Astronomical Society, 492(3), 4235-4245. https://doi.org/10.1093/mnras/staa006

Halo model is a physically intuitive method for modelling the non-linear power spectrum, especially for the alternatives to the standard ΛCDM models. In this paper, we examine the Sheth–Tormen barrier formula adopted in the previous CHAM method. As a...
