N-body Simulations of Large-Scale Structure in the Generalized Cubic Covariant Galileon Model
Luís Atayde, Noemi Frusciante, Baojiu Li
We present the first N-body simulations of structure formation in the Generalized Cubic Covariant Galileon (GCCG) model. This theory extends the cubic covariant Galileon through po…
