Universality of the halo mass function in modified gravity cosmologies

Suhani Gupta, Wojciech A. Hellwing, Maciej Bilicki +1

We study the halo mass function (HMF) in modified gravity (MG) models using a set of large $N$ -body simulations -- the ELEPHANT suite. We consider two popular beyond-general relati…

Speeding up $N$ -body simulations of modified gravity: Chameleon screening models

Sownak Bose, Baojiu Li, Alexandre Barreira +5

We describe and demonstrate the potential of a new and very efficient method for simulating certain classes of modified gravity theories, such as the widely studied $f (R)$ gravity…

Galactic halos in cosmology with long-range scalar DM interaction

Wojciech A. Hellwing

Based on a set of cosmological N-body simulations we analyze properties of the dark matter haloes (DM) in a galaxy mass range ( $1 0^{11} - 1 0^{13} h^{- 1} M_{⊙}$ ) in modified $\lc…
