Efficient numerical evolution of self-gravitating systems with dark-matter-baryon scattering
NSphere-IDM is a fast algorithm to evolve spherical dark matter and gas systems, including dark-matter–baryon scattering and radiative cooling. It simplifies complex six-dimensional phase space into three dimensions for efficiency, allowing researchers to test various dark matter interaction models quickly. This tool helps understand how these interactions affect galaxy evolution by modeling thermal changes in the gas.
