The cumulative star formation histories of dwarf galaxies with TNG50. I: environment-driven diversity and connection to quenching
Monthly Notices of the Royal Astronomical Society(2021)
摘要
We present the cumulative star formation histories (SFHs) of >15 000 dwarf galaxies ($M_{\rm *}=10^{7-10}\, {\rm M}_{\odot }$) simulated with the TNG50 run of the IllustrisTNG suite across a vast range of environments. The key factors that determine the dwarfs’ SFHs are their central/satellite status and stellar mass, with centrals and more massive dwarfs assembling their stellar mas...
