Chaos and variance in galaxy formation
Abstract
The evolution of galaxies is governed by equations with chaotic solutions: gravity and compressible (magneto-)hydrodynamics. While this microscale chaos and stochasticity has been well studied, it is poorly understood how it couples to macroscale properties examined in simulations of galaxy formation. In this paper, we use tiny perturbations introduced by floating-point round-off, random number generators, and seemingly trivial differences in …
