Is the IMF in ellipticals bottom-heavy? Clues from their chemical abundances (2018)
Journal Article
De Masi, C., Vincenzo, F., Matteucci, F., Rosani, G., La Barbera, F., Pasquali, A., & Spitoni, E. (2019). Is the IMF in ellipticals bottom-heavy? Clues from their chemical abundances. Monthly notices of the Royal Astronomical Society, 483(2), 2217-2235. https://doi.org/10.1093/mnras/sty3127

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 mass in a sample of early-...

The Gaia-ESO Survey: The N/O abundance ratio in the Milky Way (2018)
Journal Article
Magrini, L., Vincenzo, F., Randich, S., Pancino, E., Casali, G., Tautvaišienė, G., …Worley, C. (2018). The Gaia-ESO Survey: The N/O abundance ratio in the Milky Way. Astronomy and Astrophysics, 618, Article A102. https://doi.org/10.1051/0004-6361/201833224

Context. The abundance ratio N/O is a useful tool to study the interplay of galactic processes, for example star formation efficiency, timescale of infall, and outflow loading factor. Aims. We aim to trace log(N/O) versus [Fe/H] in the Milky Way and... Read More about The Gaia-ESO Survey: The N/O abundance ratio in the Milky Way.

On the [$\alpha$/Fe]-[Fe/H] relations in early-type galaxies (2018)
Journal Article
Vincenzo, F., Kobayashi, C., & Taylor, P. (2018). On the [$\alpha$/Fe]-[Fe/H] relations in early-type galaxies. Monthly Notices of the Royal Astronomical Society: Letters, 480(1), L38–L42. https://doi.org/10.1093/mnrasl/sly128

We study how the predicted [$\alpha$/Fe]-[Fe/H] relations in early-type galaxies vary as functions of their stellar masses, ages and stellar velocity dispersions, by making use of cosmological chemodynamical simulations with feedback from active gala...

Evolution of N/O ratios in galaxies from cosmological hydrodynamical simulations (2018)
Journal Article
Vincenzo, F., & Kobayashi, C. (2018). Evolution of N/O ratios in galaxies from cosmological hydrodynamical simulations. Monthly notices of the Royal Astronomical Society, 478(1), 155–166. https://doi.org/10.1093/mnras/sty1047

We study the redshift evolution of the gas-phase O/H and N/O abundances, both (i) for individual ISM regions within single spatially-resolved galaxies and (ii) when dealing with average abundances in the whole ISM of many unresolved galaxies. We make... Read More about Evolution of N/O ratios in galaxies from cosmological hydrodynamical simulations.

Extragalactic archaeology with the C, N, and O chemical abundances (2018)
Journal Article
Vincenzo, F., & Kobayashi, C. (2018). Extragalactic archaeology with the C, N, and O chemical abundances. Astronomy and Astrophysics, 610, Article L16. https://doi.org/10.1051/0004-6361/201732395

We predict how the C, N, and O abundances within the interstellar medium of galaxies evolve as functions of the galaxy star formation history (SFH). We adopt a hydrodynamical cosmological simulation, focusing on three star-forming disc galaxies with... Read More about Extragalactic archaeology with the C, N, and O chemical abundances.
