Is There a Disk of Satellites around the Milky Way? [PDF]

open access: yesThe 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 ...

PHYSICAL PROPERTIES OF MOLECULAR CLOUDS FOR THE ENTIRE MILKY WAY DISK [PDF]

open access: yes, 2016
This study presents a catalog of 8107 molecular clouds that covers the entire Galactic plane and includes 98% of the 12CO emission observed within . The catalog was produced using a hierarchical cluster identification method applied to the result of a ...

THE SPATIAL STRUCTURE OF MONO-ABUNDANCE SUB-POPULATIONS OF THE MILKY WAY DISK [PDF]

open access: yes, 2011
The spatial, kinematic, and elemental-abundance structure of the Milky Way's stellar disk is complex, and has been difficult to dissect with local spectroscopic or global photometric data.

Riding the kinematic waves in the Milky Way disk with Gaia [PDF]

open access: yesAstronomy & Astrophysics, 2018
Context. Gaia DR2 has delivered full-sky six-dimensional measurements for millions of stars, and the quest to understand the dynamics of our Galaxy has entered a new phase. Aims.

Icarus: A Flat and Fast Prograde Stellar Stream in the Milky Way Disk [PDF]

open access: yes, 2020
We explore the local volume of the Milky Way via chemical and kinematical measurements from high-quality astrometric and spectroscopic data recently released by the Gaia, APOGEE, and GALAH programs.

The Tilt of the Velocity Ellipsoid of Different Galactic Disk Populations

open access: yesThe Astrophysical Journal, 2023
The tilt of the velocity ellipsoid is a helpful tracer of the gravitational potential of the Milky Way. In this paper, we use nearly 140,000 red clump (RC) stars selected from LAMOST and Gaia to make a detailed analysis of the tilt of the velocity ...

Resonant Effects of a Bar on the Galactic Disk Kinematics Perpendicular to Its Plane

open access: yesGalaxies, 2023
Detailed analysis of kinematics of the Milky Way disk in the solar neighborhood based on the GAIA DR3 catalog reveals the existence of peculiarities in the stellar velocity distribution perpendicular to the galactic plane.

THE DISTRIBUTION OF DARK MATTER IN THE MILKY WAY’S DISK [PDF]

open access: yesThe Astrophysical Journal, 2014
We present an analysis of the effects of dissipational baryonic physics on the local dark matter (DM) distribution at the location of the Sun, with an emphasis on the consequences for direct detection experiments. Our work is based on a comparative analysis of two cosmological simulations of a Milky Way halo: Eris, a full hydrodynamic simulation, and ...

Three-dimensional Structure of the Milky Way Disk: The Distribution of Stars and Dust beyond 0.35 R☉ [PDF]

open access: yes, 2001
We present a three-dimensional model for the Milky Way fitted to the far-infrared (FIR) and near-infrared (NIR) data from the COBE/DIRBE instrument for Galactic latitudes |b| < 30° and to within 20° of the Galactic center.

Milky Way's thick and thin disk: Is there a distinct thick disk? [PDF]

open access: yesAstronomische Nachrichten, 2016
AbstractThis article is based on our discussion session on Milky Way models at the 592 WE‐Heraeus Seminar, Reconstructing the Milky Way's History: Spectroscopic Surveys, Asteroseismology and Chemodynamical Models. The discussion focused on the following question: “Are there distinct thick and thin disks?”.
