C. Gareth Few, Stephanie Courty, Brad K. Gibson
TL;DR
RAMSES-CH is an innovative chemodynamical simulation code that combines adaptive mesh refinement with detailed chemical evolution tracking in cosmological volumes, enabling high-resolution studies of galaxy formation.
Contribution
It introduces the first chemodynamical code to self-consistently evolve chemical elements at sub-kiloparsec resolution in cosmological simulations.
Findings
First to combine Eulerian hydrodynamics with chemical evolution in cosmology.
Enables detailed study of chemical abundance ratios in galaxy formation.
Maintains sub-kiloparsec resolution in large-scale simulations.
Abstract
We present a new chemodynamical code based on the adaptive mesh refinement code RAMSES. The new code uses Eulerian hydrodynamics and N-body dynamics in a cosmological framework to trace the production and advection of several chemical species. It is the first such code to follow the self-consistent evolution of chemical elements in cosmological volumes while maintaining sub-kiloparsec resolution. The code will be used to simulate disk galaxies and explore the influence of chemical evolution models and star formation on galactic abundance ratios.
