An [$α$/Fe]-enhanced thick disk in a Milky Way Analogue [PDF]
, 2021 The Milky Way disk consists of two prominent components - a thick, alpha-rich, low-metallicity component and a thin, metal-rich, low-alpha component. External galaxies have been shown to contain thin and thick disk components, but whether distinct components in the [$\alpha$/Fe]-[Z/H] plane exist in other Milky Way-like galaxies is not yet known.

Phylogeny of the Milky Way’s inner disk and bulge populations: Implications for gas accretion, (the lack of) inside-out thick disk formation, and quenching [PDF]
Astronomy & Astrophysics, 2018 We show that the bulge and the disk of the Milky Way (MW) at R ≲ 7 kpc are well described by a unique chemical evolution and a two-phase star formation history (SFH). We argue that the populations within this inner disk, not the entire disk, are the same,

Tracing the formation of the Milky Way through ultra metal-poor stars [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We use Gaia DR2 astrometric and photometric data, published radial velocities and MESA models to infer distances, orbits, surface gravities, and effective temperatures for all ultra metal-poor stars ([Fe/H] 11 Gyr) and that they are expected to belong to

The Vertical Displacement of the Milky Way Disk [PDF]
Formation and Evolution of Galaxy Outskirts, Proceedings of the
International Astronomical Union, IAU Symposium, Volume 321, pp. 13-15, 2017, 2017 An oscillating vertical displacement of the Milky Way, with a wavelength of about 8 kpc and and amplitude of about 100 pc (increasing with distance from the Galactic center) is observed towards the Galactic anticenter. These oscillations are thought to be the result of disk perturbations from dwarf satellites of the Milky Way.

Early formation and recent starburst activity in the nuclear disk of the Milky Way [PDF]
, 2019 The nuclear disk is a dense stellar structure at the centre of the Milky Way, with a radius of ~150 pc (ref. 1 ). It has been a place of intense star formation in the past several tens of millions of years 1 – 3 , but its overall formation history has ...

High-Mass Star and Massive Cluster Formation in the Milky Way [PDF]
Annual Review of Astronomy and Astrophysics, 2017 This review examines the state-of-the-art knowledge of high-mass star and massive cluster formation, gained from ambitious observational surveys, which acknowledges the multiscale characteristics of these processes.

, 1997 We review observational evidence bearing on the formation of a prototypical large spiral galaxy, the Milky Way. New ground- and space-based studies of globular star clusters and dwarf spheroidal galaxies provide a wealth of information to constrain theories of galaxy formation.

Star Formation in the Local Milky Way [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractStudies of molecular clouds and young stars near the sun have provided invaluable insights into the process of star formation. Indeed, much of our physical understanding of this topic has been derived from such studies. Perhaps the two most fundamental problems confronting star formation research today are: 1) determining the origin of stellar ...
