Balance among gravitational instability, star formation and accretion determines the structure and evolution of disc galaxies

Forbes, John C.; Krumholz, Mark; Burkert, Andreas; Dekel, A


Over the past 10 Gyr, star-forming galaxies have changed dramatically, from clumpy and gas rich, to rather quiescent stellar-dominated discs with specific star formation rates lower by factors of a few tens. We present a general theoretical model for how this transition occurs, and what physical processes drive it, making use of 1D axisymmetric thin disc simulations with an improved version of the Gravitational Instability-Dominated Galaxy Evolution Tool (GIDGET) code. We show that at every...[Show more]
