Rapid simulation rescaling from standard to modified gravity models
Alexander Mead, John Peacock, Lucas Lombriser +1
We develop and test an algorithm to rescale a simulated dark-matter particle distribution or halo catalogue from a standard gravity model to that of a modified gravity model. This…
How chameleons core dwarfs with cusps
Lucas Lombriser, Jorge Peñarrubia
The presence of a scalar field that couples nonminimally and universally to matter can enhance gravitational forces on cosmological scales while restoring general relativity in the…
Classifying Linearly Shielded Modified Gravity Models in Effective Field Theory
Lucas Lombriser, Andy Taylor
We study the model space generated by the time-dependent operator coefficients in the effective field theory of the cosmological background evolution and perturbations of modified…
Constraining chameleon models with cosmology
Lucas Lombriser
Chameleon fields may modify gravity on cluster scales while recovering general relativity locally. This article reviews signatures of chameleon modifications in the nonlinear cosmo…
Halo model and halo properties in Galileon gravity cosmologies
Alexandre Barreira, Baojiu Li, Wojciech A. Hellwing +3
We investigate the performance of semi-analytical modelling of large-scale structure in Galileon gravity cosmologies using results from N-body simulations. We focus on the Cubic an…
