The Global Structure and Evolution of a Self-Gravitating Multiphase Interstellar Medium in a Galactic Disk
Using high-resolution, two-dimensional hydrodynamical simulations, we investigate the evolution of a self-gravitating multiphase interstellar medium in the central kiloparsec region of a galactic disk. We find that a gravitationally and thermally unstable disk evolves, in a self-stabilizing manner, into a globally quasi-stable disk that consists of cold (T<100 K), dense …
