Runaway stars masquerading as star formation in galactic outskirts
Eric P. Andersson, Florent Renaud, Oscar Agertz
In the outskirts of nearby spiral galaxies, star formation is observed in extremely low gas surface densities. Star formation in these regions, where the interstellar medium is dom…
VINTERGATAN I: The origins of chemically, kinematically and structurally distinct discs in a simulated Milky Way-mass galaxy
Oscar Agertz, Florent Renaud, Sofia Feltzing +6
Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical and kinematical structures that encode its history. In this work, we study their origins using a cosm…
VINTERGATAN III: how to reset the metallicity of the Milky Way
Florent Renaud, Oscar Agertz, Eric P. Andersson +5
Using the cosmological zoom simulation VINTERGATAN, we present a new scenario for the onset of star formation at the metal-poor end of the low-[/Fe] sequence in a Milky Way-like…
VINTERGATAN II: the history of the Milky Way told by its mergers
Florent Renaud, Oscar Agertz, Justin I. Read +5
Using the VINTERGATAN cosmological zoom simulation, we explore the contributions of the in situ and accreted material, and the effect of galaxy interactions and mergers in the asse…
How runaway stars boost galactic outflows
Eric P. Andersson, Oscar Agertz, Florent Renaud
Roughly ten per cent of OB stars are kicked out of their natal clusters before ending their life as supernovae. These so-called runaway stars can travel hundreds of parsecs into th…
