The AGORA High-Resolution Galaxy Simulations Comparison Project. II: Isolated Disk Test

Understand

Using an isolated Milky Way-mass galaxy simulation, we compare results from 9 state-of-the-art gravito-hydrodynamics codes widely used in the numerical community.

• We utilize the infrastructure we have built for the AGORA High-resolution Galaxy Simulations Comparison Project.
• This includes the common disk initial conditions, common physics models (e.g., radiative cooling and UV background by the standardized package Grackle) and common analysis toolkit yt, all of which are publicly available.
• Subgrid physics models such as Jeans pressure floor, star formation, supernova feedback energy, and metal production are carefully constrained across code platforms.
