Chemical evolution of the Milky Way: constraints on the formation of the thick and thin discs [PDF]
, 2020 We study the evolution of Milky Way thick and thin discs in the light of the most recent observational data. In particular, we analyze abundance gradients of O, N, Fe and Mg along the thin disc as well as the [Mg/Fe] vs.

The Milky Way as a Star Formation Engine [PDF]
, 2014 The cycling of material from the interstellar medium (ISM) into stars and the return of stellar ejecta into the ISM is the engine that drives the "galactic ecology" in normal spirals, a cornerstone in the formation and evolution of galaxies through cosmic time.

A low pre-infall mass for the Carina dwarf galaxy from disequilibrium modelling [PDF]
, 2015 Dark matter only simulations of galaxy formation predict many more subhalos around a Milky Way like galaxy than the number of observed satellites. Proposed solutions require the satellites to inhabit dark matter halos with masses between one to ten ...

Traces of the formation history of the Milky Way [PDF]
Proceedings of the International Astronomical Union, 2013 AbstractChemical and kinematical information is needed in order to understand and trace the formation history of our Galaxy. In the homogeneous large sample of F and G stars in the survey by Nordström et al. (2004), groups of stars with orbital parameters different from field stars were found by Helmi et al. (2006).

A Model for the Formation of the Milky Way [PDF]
Publications of the Astronomical Society of Australia, 2004 AbstractA new chemodynamical model for the formation and evolution of a Milky Way type galaxy is introduced. In this scenario, the galaxy forms inside a slowly growing dark matter halo in a ΛCDM cosmology. In contrast to the simple merger and collapse scenarios, the galactic mass grows continuously over a Hubble time.

The connection between the host halo and the satellite galaxies of the Milky Way [PDF]
, 2016 Many properties of the Milky Way's dark matter halo, including its mass assembly history, concentration, and subhalo population, remain poorly constrained.

Life in the fast lane: a direct view of the dynamics, formation, and evolution of the Milky Way’s bar [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Studies of the ages, abundances, and motions of individual stars in the Milky Way provide one of the best ways to study the evolution of disc galaxies over cosmic time.

Dust formation in Milky Way-like galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We introduce a dust model for cosmological simulations implemented in the moving-mesh code AREPO and present a suite of cosmological hydrodynamical zoom-in simulations to study dust formation within galactic haloes. Our model accounts for the stellar production of dust, accretion of gas-phase metals onto existing grains, destruction of dust through ...

GTC Follow-up Observations of Very Metal-poor Star Candidates from DESI
The Astrophysical Journal, 2023 The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ∼10, improving the sample statistics to study the early chemical evolution of the Milky Way ...
