Vertical disc heating in Milky Way-sized galaxies in a cosmological context
Vertical disc heating in Milky Way-sized galaxies in a cosmological context
Vertically extended, high velocity dispersion stellar distributions appear to be a ubiquitous feature of disc galaxies, and both internal and external mechanisms have been proposed to be the major driver of their formation. However, it is unclear to what extent each mechanism can generate such a distribution, which is likely …
