Three-Dimensional Numerical Simulations of Thermal-Gravitational Instability in Protogalactic Halo Environment

Abstract

We study thermal-gravitational instability in simplified models for protogalactic halos using three-dimensional hydrodynamic simulations. The simulations started with isothermal density perturbations of various power spectra, and followed the evolution of gas with radiative cooling down to T = 10 K, background heating, and self-gravity for up to ∼ 20… (More)
