The Milky Way’s Rowdy Neighbors: The Effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disk

The Astrophysical Journal
The Milky Way (MW) is a barred spiral galaxy shaped by tidal interactions with its satellites. The Large Magellanic Cloud (LMC) and the Sagittarius dwarf galaxy (Sgr) are the dominant influences at the present day. This paper presents a suite of four 10 ^

ON THE FORMATION OF THE DISK OF SATELLITES OF THE MILKY WAY: SIMULATION OF THE COLLISION OF TWO GALAXIES

Momento, 2014
At present there is some evidence showing that the satellite galaxies of the Milky Way might be distributed on a disc structure, known as the disc of satellites.

Predictions for the Detectability of Milky Way Satellite Galaxies and Outer-Halo Star Clusters with the Vera C. Rubin Observatory

The Open Journal of Astrophysics
We predict the sensitivity of the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) to faint, resolved Milky Way satellite galaxies and outer-halo star clusters.

Gas Transfer between the Inner 3 kpc Disk and the Galactic Central Molecular Zone

The Astrophysical Journal
We uncovered a more tilted molecular gas structure with highly negative velocities located near the dust lane. Our observations show that the approaching gas flows from the overshoot process are captured by the gravitational potential of the bar and then

Andromeda galaxy vs Milky Way galaxy

Communications of the Byurakan Astrophysical Observatory
Some physical features of the Andromeda galaxy are compared with their counterparts in the Milky Way to demonstrate that the Andromeda galaxy has traversed a longer evolutionary path. One of the evolutionary dependents in galaxies is the metallicity factor. The metallicity radial gradient in galaxies can also be used for this purpose.

Revealing Gas Inflows Toward the Galactic Central Molecular Zone

The Astrophysical Journal Letters
We study the gas inflows toward the Galactic Central Molecular Zone (CMZ) based on the gas morphological and kinematic features from the Milky Way Imaging Scroll Painting in the region of l = 1.°2–19.°0 and ∣ b ∣ ≲ 3.°0.

Linnutee [PDF]

Mäetagused, 2002
Astronomically, the Milky Way is a big star system _ a galaxy. The word galaxy is derived from the Greek gala `milk'. In many languages the Milky Way's name is connected with milk. However, in Estonia this form of the name is rare.

A Wave-corrected Assessment of the Local Midplane

The Astrophysical Journal
As the number of known Galactic structures mounts thanks to the Gaia Space Telescope, it is now pertinent to study methods for disentangling structures occupying the same regions of the Milky Way. Indeed, understanding the precise form of each individual

The Structure, Populations, and Kinematics of the Milky Way Central and Inner Bulge with OGLE, APOGEE, and Gaia Data

The Astrophysical Journal
We present an analysis of the structure, kinematics, and chemo-dynamical properties of the Milky Way bulge using RR Lyrae stars from Optical Gravitational Lensing Experiment (OGLE), and giant stars from APOGEE and Gaia that have distances placing them in

Differential Accretion of Ionized Low-velocity Gas at the Milky Way’s Disk–Halo Interface

The Astrophysical Journal
We measure line-of-sight velocities of metal absorption and H I emission along 132 QSO sight lines in order to study gas accretion and outflow at the disk–halo interface of the Milky Way.
