Future astronomical surveys will gather information that will allow gravity to be tested on cosmological scales, where general relativity is currently poorly constrained. We present a set of cosmological hydrodynamical simulations that follow galaxy... Read More about Realistic simulations of galaxy formation in f(R) modified gravity.

A new smooth-k space filter approach to calculate halo abundances (2018)
Journal Article
Leo, M., Baugh, C. M., Li, B., & Pascoli, S. (2018). A new smooth-k space filter approach to calculate halo abundances. Journal of Cosmology and Astroparticle Physics, 2018(04), Article 010. https://doi.org/10.1088/1475-7516/2018/04/010

We propose a new filter, a smooth-k space filter, to use in the Press-Schechter approach to model the dark matter halo mass function which overcomes shortcomings of other filters. We test this against the mass function measured in N-body simulations.... Read More about A new smooth-k space filter approach to calculate halo abundances.
