Galactic stellar and substellar initial mass function
TL;DR: A review of the present-day mass function and initial mass function in various components of the Galaxy (disk, spheroid, young, and globular clusters) and in conditions characteristic of early star formation is presented in this paper.

TL;DR: In this paper, the authors used the photometric parallax method to estimate the distances to ~48 million stars detected by the Sloan Digital Sky Survey (SDSS) and map their three-dimensional number density distribution in the Galaxy.
Journal ArticleDOI
The New Galaxy: Signatures of Its Formation
TL;DR: The formation and evolution of galaxies is one of the great outstanding problems of astrophysics as discussed by the authors, and a detailed physical picture where individual stellar populations can be associated with (tagged to) elements of the protocloud is far beyond our current understanding.
Journal ArticleDOI
The Galaxy in Context: Structural, Kinematic, and Integrated Properties
TL;DR: In this paper, the authors review the key integrated, structural and kinematic parameters of the Galaxy, and point to uncertainties as well as directions for future progress, and show that the Galaxy is a luminous (L⋆) barred spiral with a central box/peanut bulge, a dominant disk, and a diffuse stellar halo.
Journal ArticleDOI
Elemental abundance survey of the Galactic thick disc
TL;DR: In this paper, an abundance analysis for F- and G- dwarfs of the Galactic thick-disc component was performed using accurate radial velocities combined with the Hipparcos astrometry, kinematics (U, V and W) and Galactic orbital parameters.
