    • Is the IMF in ellipticals bottom-heavy? Clues from their chemical abundances 

      Masi, C. De; Vincenzo, F.; Matteucci, F.; Rosani, G.; Barbera, La; Pasquali, A.; Spitoni, E. (2019-02)
      We tested the implementation of different initial mass functions (IMFs) in our model for the chemical evolution of ellipticals, with the aim of reproducing the observed relations of [Fe/H] and [Mg/Fe] abundances with galaxy ...
