The Milky Way's Stellar Disk [PDF]
The Astronomy and Astrophysics Review, 2013 A suite of vast stellar surveys mapping the Milky Way, culminating in the Gaia mission, is revolutionizing the empirical information about the distribution and properties of stars in the Galactic stellar disk.

The Dark Disk of the Milky Way [PDF]
The Astrophysical Journal, 2009 Massive satellite accretions onto early galactic disks can lead to the deposition of dark matter in disk-like configurations that co-rotate with the galaxy. This phenomenon has potentially dramatic consequences for dark matter detection experiments.

, 2015 This review summarises the invited presentation I gave on the Milky Way disc. The idea underneath was to touch those topics that can be considered hot nowadays in the Galactic disk research: the reality of the thick disk, the spiral structure of the ...

HII Region Metallicity Distribution in the Milky Way Disk [PDF]
The Astrophysical Journal, 2011 The distribution of metals in the Galaxy provides important information about galaxy formation and evolution. HII regions are the most luminous objects in the Milky Way at mid-infrared to radio wavelengths and can be seen across the entire Galactic disk.

Chemodynamical evolution of the Milky Way disk [PDF]
Astronomy & Astrophysics, 2013 In the first paper of this series, we present a new approach for studying the chemo-dynamical evolution in disk galaxies, which consists of fusing disk chemical evolution models with compatible numerical simulations of galactic disks. This method avoids known star formation and chemical enrichment problems encountered in simulations.

Unveiling a Young Thick Disk in the Milky Way
The Astrophysical Journal LettersThe thickness of a galaxy’s disk provides a valuable probe of its formation and evolution history. Observations of the Milky Way and local galaxies have revealed an ubiquitous disk structure with two distinctive components: an old thick disk and a ...

Is There a Disk of Satellites around the Milky Way? [PDF]
The Astrophysical Journal, 2017 Abstract The “disk of satellites” (DoS) around the Milky Way is a highly debated topic with conflicting interpretations of observations and their theoretical models. We perform a comprehensive analysis of all of the dwarfs detected in the Milky Way and find that the DoS structure depends strongly on the plane identification method and ...

International Astronomical Union Colloquium, 1989 A warped disk in our own galaxy is evident by means of HI, HII, γ-rays and dust observations, but unexistent when star distributions are considered, specially those of late type stars. This fact is in disagreement with the theories which assume a gravitational origin of warps, for instance a tidal interaction with the Magellanic Clouds.

DETECTING THE MILKY WAY'S DARK DISK [PDF]
The Astrophysical Journal, 2009 In LambdaCDM, massive satellites are dragged into the disk-plane by dynamical friction where they dissolve into a stellar thick disk and a more massive dark matter disk. The distinctive kinematics of the dark disk matches the stars that also entered in the satellites.
