Chemical evolution of the Milky Way: constraints on the formation of the thick and thin discs (2020)
Journal Article
Palla, M., Matteucci, F., Spitoni, E., Vincenzo, F., & Grisoni, V. (2020). Chemical evolution of the Milky Way: constraints on the formation of the thick and thin discs. Monthly notices of the Royal Astronomical Society, 498(2), 1710-1725. https://doi.org/10.1093/mnras/staa2437

We study the evolution of Milky Way thick and thin discs in the light of the most recent observational data. In particular, we analyse abundance gradients of O, N, Fe, and Mg along the thin disc as well as the [Mg/Fe] versus [Fe/H] relations and the...

In order to understand the roles of metal flows in galaxy formation and evolution, we analyse our self-consistent cosmological chemo-dynamical simulation of a Milky Way like galaxy during its thin-disc phase. Our simulated galaxy disc qualitatively r... Read More about Stellar migrations and metal flows -- Chemical evolution of the thin disc of a simulated Milky Way analogous galaxy.

The influence of a top-heavy integrated galactic IMF and dust on the chemical evolution of high-redshift starbursts (2020)
Journal Article
Palla, M., Calura, F., Matteucci, F., Fan, X. L., Vincenzo, F., & Lacchin, E. (2020). The influence of a top-heavy integrated galactic IMF and dust on the chemical evolution of high-redshift starbursts. Monthly notices of the Royal Astronomical Society, 494(2), 2355-2373. https://doi.org/10.1093/mnras/staa848

We study the effects of the integrated galactic initial mass function (IGIMF) and dust evolution on the abundance patterns of high redshift starburst galaxies. In our chemical models, the rapid collapse of gas clouds triggers an intense and rapid sta...

We test the integrated galactic initial mass function (IGIMF) on the chemical evolution of 16 ultrafaint dwarf (UFD) galaxies discussing in detail the results obtained for three of them: Boötes I, Boötes II, and Canes Venatici I, taken as prototypes...

Age dating of an early Milky Way merger via asteroseismology of the naked-eye star ν Indi (2020)
Journal Article

Over the course of its history, the Milky Way has ingested multiple smaller satellite galaxies1. Although these accreted stellar populations can be forensically identified as kinematically distinct structures within the Galaxy, it is difficult in gen...
