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…
Inverse non-metricity in gravity: cosmology and observational constraints
LuÃs Atayde, Simão Marques Nunes, Noemi Frusciante
We study a minimal modified gravity scenario in the symmetric teleparallel (non-metricity) formulation, focusing on an inverse non-metricity term with . The mode…
Matter Power Spectra in Modified Gravity: A Comparative Study of Approximations and -Body Simulations
Benjamin Bose, Ashim Sen Gupta, Bartolomeo Fiorini +9
Testing gravity and the concordance model of cosmology, CDM, at large scales is a key goal of this decade's largest galaxy surveys. Here we present a comparative study of dark…
Non-linear power spectrum and forecasts for Generalized Cubic Covariant Galileon
LuÃs Atayde, Noemi Frusciante, Benjamin Bose +2
To fully exploit the data from next generation surveys, we need an accurate modelling of the matter power spectrum up to non-linear scales. Therefore in this work we present the ha…
