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…
