Disc galaxies are still settling

2023
Lorsque les disques galactiques se déposent et deviennent suffisamment massifs, ils sont capables de former des barres stellaires. Ces structures non axisymétriques induisent des chocs dans le gaz, le faisant s'écouler vers le centre où se forment des structures nucléaires, telles que des disques et des anneaux nucléaires.

The evolution of disc galaxies

Philosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2000
We briefly describe the physical processes that are included in our semi–analytic model of hierarchical galaxy formation. We review some of the low redshift properties of one such model constructed assuming a ∧ CDM cosmology. We examine the evolutionary paths of typical bright disc galaxies in this model.

Modelling Neutral Hydrogen Discs of Spiral Galaxies

Chinese Physics Letters, 2002
We present an analytical model of a neutral hydrogen disc in a spiral galaxy. The gas disc of the spiral galaxy is assumed to have an exponential surface density profile and to be ionized by the cosmic ultraviolet background. To compare with observations, we consider the disc position angle and inclination angle for a line of sight going through the ...
