Nitrogen and oxygen abundances in the Local Universe (2016)
Journal Article
Vincenzo, F., Belfiore, F., Maiolino, R., Matteucci, F., & Ventura, P. (2016). Nitrogen and oxygen abundances in the Local Universe. Monthly notices of the Royal Astronomical Society, 458(4), 3466–3477. https://doi.org/10.1093/mnras/stw532

We present chemical evolution models aimed at reproducing the observed (N/O) vs. (O/H) abundance pattern of star forming galaxies in the Local Universe. We derive gas-phase abundances from SDSS spectroscopy and a complementary sample of low-metallici... Read More about Nitrogen and oxygen abundances in the Local Universe.

Are ancient dwarf satellites the building blocks of the Galactic halo? (2016)
Journal Article
Spitoni, E., Vincenzo, F., Matteucci, F., & Romano, D. (2016). Are ancient dwarf satellites the building blocks of the Galactic halo?. Monthly notices of the Royal Astronomical Society, 458(3), 2541-2552. https://doi.org/10.1093/mnras/stw519

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 spheroidal satellites of th... Read More about Are ancient dwarf satellites the building blocks of the Galactic halo?.

Modern yields per stellar generation: the effect of the IMF (2015)
Journal Article
Vincenzo, F., Matteucci, F., Belfiore, F., & Maiolino, R. (2016). Modern yields per stellar generation: the effect of the IMF. Monthly notices of the Royal Astronomical Society, 455(4), 4183–4190. https://doi.org/10.1093/mnras/stv2598

Gaseous and stellar metallicities in galaxies are nowadays routinely used to constrain the evolutionary processes in galaxies. This requires the knowledge of the average yield per stellar generation, $y_{\text{Z}}$, i.e. the quantity of metals that a...

The IGIMF and other IMFs in dSphs: the case of Sagittarius (2015)
Journal Article
Vincenzo, F., Matteucci, F., Recchi, S., Calura, F., McWilliam, A., & A. Lanfranchi, G. (2015). The IGIMF and other IMFs in dSphs: the case of Sagittarius. Monthly notices of the Royal Astronomical Society, 449(2), 1327–1339. https://doi.org/10.1093/mnras/stv357

We have studied the effects of various initial mass functions (IMFs) on the chemical evolution of the Sagittarius dwarf galaxy (Sgr). In particular, we tested the effects of the integrated galactic initial mass function (IGIMF) on various predicted a... Read More about The IGIMF and other IMFs in dSphs: the case of Sagittarius.

Chemical evolution of classical and ultra-faint dwarf spheroidal galaxies (2014)
Journal Article
Vincenzo, F., Matteucci, F., Vattakunnel, S., & A. Lanfranchi, G. (2014). Chemical evolution of classical and ultra-faint dwarf spheroidal galaxies. Monthly notices of the Royal Astronomical Society, 441(4), 2815–2830. https://doi.org/10.1093/mnras/stu710

We present updated chemical evolution models of two dwarf spheroidal galaxies (Sculptor and Carina) and the first detailed chemical evolution models of two ultra-faint dwarfs (Hercules and Bo\"otes I). Our results suggest that the dwarf spheroidals e... Read More about Chemical evolution of classical and ultra-faint dwarf spheroidal galaxies.
