    • Are ancient dwarf satellites the building blocks of the Galactic halo? 

      Spitoni, Emanuele; Vincenzo, F.; Matteucci, Francesca; Romano, D. (2016-05-21)
      According to the current cosmological cold dark matter paradigm, the Galactic halo could have been the result of the assemblage of smaller structures. Here we explore the hypothesis that the classical and ultra-faint dwarf ...

    • The Gaia-ESO Survey : the N/O abundance ratio in the Milky Way 

      Magrini, L.; Vincenzo, F.; Randich, S.; Pancino, E.; Casali, G.; Tautvaisiene, G.; Drazdauskas, A.; Mikolaitis, S.; Minkeviciute, R.; Stonkute, E.; Chorniy, Y.; Bagdonas, V.; Kordopatis, G.; Frie, E.; Roccatagliata, V.; Jimenez-Esteban, F. M.; Gilmore, G.; Vallenari, A.; Bensby, T.; Bragaglia, A.; Korn, A. J.; Lanzafame, A. C.; Smiljanic, R.; Bayo, A.; Casey, A. R.; Costado, M. T.; Franciosini, E.; Hourihane, A.; Jofré, P.; Lewis, J.; Monaco, L.; Morbidelli, L.; Sacco, G.; Worley, C. (2018-10-01)
      Context. The abundance ratio N/O is a useful tool to study the interplay of galactic processes, for example star formation e ciency, timescale of infall, and outflow loading factor. Aims. We aim to trace log(N/O) versus ...

    • 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 ...

    • New analytical solutions for chemical evolution models: : characterizing the population of star-forming and passive galaxies 

      Spitoni, Emanuele; Vincenzo, F.; Matteucci, Francesca (2017-03-01)
      Context. Analytical models of chemical evolution, including inflow and outflow of gas, are important tools for studying how the metal content in galaxies evolves as a function of time. Aims. We present new analytical ...
