On the stellar halo metallicity profile of Milky Way-like galaxies in the Auriga simulations
Antonela Monachesi, Facundo A. Gomez, Robert J. J. Grand +5
A recent observational study of haloes of nearby Milky Way-like galaxies shows that only half (four out of eight) of the current sample exhibits strong negative metallicity ([Fe/H]…
Vertical disc heating in Milky Way-sized galaxies in a cosmological context
Robert J. J. Grand, Volker Springel, Facundo A. Gómez +4
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…
A fully cosmological model of a Monoceros-like ring
Facundo A. Gómez, Simon D. M. White, Federico Marinacci +4
We study the vertical structure of a stellar disk obtained from a fully cosmological high-resolution hydrodynamical simulation of the formation of a Milky Way-like galaxy. At the p…
