Description
In this talk, I will present the current status and first results of PANDA. PANDA is a modified version of the TreePM N-body solver Gadget-4, extended to include Modified Gravity within the Effective Field Theory framework, enabling simulations across the broad class of Horndeski theories. In particular, PANDA implements a mapping of general Horndeski models through a set of parameters modifying the standard particle dynamics, both in real and Fourier spaces, according to the linearised approach of EFTofDE. Additionally, to ensure consistency with the full non-linear theories, and reproduce the correct dynamics at small scales, PANDA implements a phenomenological screening mechanism, exploring both environment- and scale-dependent approaches. I will present the general structure of the code, its current limitations, and its potential applications to large-scale cosmological simulations of structure formation.
