On the Corotation of Milky Way Satellites: LMC-mass Satellites Induce Apparent Motions in Outer Halo Tracers

open access: yesThe Astrophysical Journal
Understanding the physical mechanism behind the formation of a corotating thin plane of satellite galaxies, like the one observed around the Milky Way (MW), has been challenging.

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

open access: yesThe 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 ^

That’s So Retro: The Gaia-Sausage-Enceladus Merger Trajectory as the Origin of the Chemical Abundance Bimodality in the Milky Way Disk

open access: yesThe Astrophysical Journal
The Milky Way (MW) is thought to have experienced a ∼3:1 mass-ratio merger event near redshift z  ∼ 2 with a significantly retrograde trajectory. This now-disrupted dwarf galaxy is commonly known as the Gaia-Sausage-Enceladus (GSE).

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

open access: yesThe 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

open access: yesThe 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

Milky Way Morphology [PDF]

open access: yes, 2019
From our limited perspective—living on a planet that orbits one of several hundred billion stars inside the Milky Way—the detailed structure of our home galaxy is difficult to determine.

Understanding the Nature of Dark Matter Halos and Galaxy Formation Through the Lens of the Milky Way

open access: yes, 2022
The Universe is full of a zoo of galaxies that serve as beacons tracing the underlying structure of dark matter in the Universe. Galaxies exhibit a diverse array of structural properties and observed brightnesses, all of which provide clues to their ...

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

open access: yesMomento, 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.
