Why do disk galaxies present a common gas-phase metallicity gradient?
Published online by Cambridge University Press: 21 March 2017
Extract
CALIFA data show that isolated disk galaxies present a common gas-phase metallicity gradient, with a characteristic slope of -0.1dex/re between 0.3 and 2 disk effective radius re (Sanchez et al. 2014). Here we construct a simple model to investigate which processes regulate the formation and evolution.
