Vertical Structure of the Milky Way Disk with Gaia DR3 [PDF]
Galaxies, 2023 Using a complete sample of about 330,000 dwarf stars, well measured by Gaia DR3, limited to the galactic north and south solid angles |b|700 pc and points to the presence of more stars beyond the thin disk that cannot be accounted for by the two-disk ...

A dynamically young and perturbed Milky Way disk [PDF]
Nature, 2018 The evolution of the Milky Way disk, which contains most of the stars in the Galaxy, is affected by several phenomena. For example, the bar and the spiral arms of the Milky Way induce radial migration of stars and can trap or scatter stars close to orbital resonances.

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.

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.

Does the Milky Way have a Maximal Disk? [PDF]
The Astrophysical Journal, 1996 The Milky Way is often considered to be the best example of a spiral for which the dark matter not only dominates the outer kinematics, but also plays a major dynamical role in the inner galaxy: the Galactic disk is therefore said to be ``sub-maximal ...

Substructure depletion in the Milky Way halo by the disk [PDF]
The Astrophysical Journal, 2009 We employ numerical simulations and simple analytical estimates to argue that dark matter substructures orbiting in the inner regions of the Galaxy can be efficiently destroyed by disk shocking, a dynamical process known to affect globular star clusters.

, 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 ...

THE MILKY WAY HAS NO DISTINCT THICK DISK [PDF]
, 2012 Different stellar sub-populations of the Milky Way's stellar disk are known to have different vertical scale heights, their thickness increasing with age. Using SEGUE spectroscopic survey data, we have recently shown that mono-abundance sub-populations, defined in the [ /Fe]-[Fe/H] space, are well described by single exponential spatial-density ...
