The age structure of stellar populations in the solar vicinity. Clues of a two-phase formation history of the Milky Way disk [PDF]

open access: bronze, 2013
We analyze a sample of solar neighborhood stars that have high-quality abundance determinations and show that there are two distinct regimes of [α/Fe] versus age, which we identify as the epochs of the thick and thin disk formation.

AZIMUTHAL METALLICITY STRUCTURE IN THE MILKY WAY DISK [PDF]

open access: yesThe Astrophysical Journal, 2015
Elemental abundance patterns in the Galactic disk constrain theories of the formation and evolution of the Milky Way. H ii region abundances are the result of billions of years of chemical evolution.

ACTION-BASED DYNAMICAL MODELING FOR THE MILKY WAY DISK [PDF]

open access: yesThe Astrophysical Journal, 2016
We present RoadMapping, a full-likelihood dynamical modeling machinery that aims to recover the Milky Way’s (MW) gravitational potential from large samples of stars in the Galactic disk.

The Milky Way and the evolution of disk galaxies

open access: green, 2002
We present a phenomenological approach to the study of disk galaxy evolution, based on i) a detailed modelling of the Milky Way (used as a prototype disk galaxy) and ii) an extension of the model to other disks through some simple scaling relations, obtained in the framework of Cold Dark matter models.

The evolution of stellar metallicity gradients of the Milky Way disk from LSS-GAC main sequence turn-off stars: a two-phase disk formation history? [PDF]

open access: bronze, 2015
Accurate measurements of stellar metallicity gradients in the radial and vertical directions of the disk and their temporal variations provide important constraints on the formation and evolution of the Milky Way disk.

Chemodynamical evolution of the Milky Way disk II: Variations with Galactic radius and height above the disk plane [PDF]

open access: bronze, 2014
the date of receipt and acceptance should be inserted later Abstract. In the first paper of this series (paper I) we presented a new approach for studying the chemodynamical evolution in disk galaxies, focusing on the Milky Way.

Hierarchical star formation in the Milky Way disk [PDF]

open access: yesThe Astrophysical Journal, 2009
Hierarchical star formation leads to a progressive decrease in the clustering of star clusters both in terms of spatial scale and age. Consistently, the statistical analysis of positions and ages of clusters in the Milky Way disk strongly suggests that a
