The NIVARIA-Local Group simulations: Unveiling the origin of rotation curve diversity in dwarf galaxies and its connection to galaxy morphology
A. Contreras-Santos, A. Di Cintio, A. Negri +7
Dwarf galaxies exhibit a large diversity in rotation curve shapes, challenging galaxy formation models within the CDM paradigm. We present NIVARIA-LG, a new suite of cosmologica…
A two-stage settling of the Milky Way disk revealed by precise ChronoGal ages
David Mirabal, Carme Gallart, Tomás Ruiz-Lara +9
The spatial distribution of Galactic disk stars of different ages and metallicities encodes its dynamical evolution history and formation pathways. The lack of precise ages for lar…
HI-bearing dark galaxies predictions from constrained Local Group simulations: how many and where to find them
Guacimara García-Bethencourt, Arianna Di Cintio, Sébastien Comerón +7
Dark galaxies are small, DM-dominated halos whose gas remains in hydrostatic and thermal equilibrium and has never formed stars. They are of particular interest because they repres…
