The Birth, Death, and Rebirth of the Milky Way Galaxy

, 2012
Kautsch’s talk will discuss the formation and evolution of the Milky Way system, which was born from a collapsing gas reservoir embedded in a dark matter halo. After its birth, the galaxy evolved and interacted with other galaxies.

Intergalactic Wandering Stars in the Local Universe: Theoretical Predictions for Their Distance and Luminosity Distribution

The Astrophysical Journal
Intergalactic wandering stars (IWSs) within 10 Mpc remain a poorly explored area of astronomy. Such stars, if they exist, are supposed to be wandering objects as they are not bound by the gravitational potential of any galaxy.

The evolution of dark matter substructure [PDF]

, 2001
This thesis investigates the dynamical evolution of systems orbiting within deeper potentials. Initially we use a simple satellite-halo interaction to study the dynamical processes that act on orbiting systems and we compare these results to analytical ...

Constraining the Geometry of Galactic Dark Matter with Gaia Data Release 3

The Astrophysical Journal
We derive both the midplane and off-plane rotation curves, v _c ( R ,  z ), and the vertical acceleration, a _z ( R ,  z ), of the Milky Way (MW) using Gaia third data release over the ranges of vertical heights z  ∈ (−2,2) kpc and galactocentric ...

The Milky Way Galaxy

, 2009
This website provides a tutorial for students about the bulge, disk, and halo components of the Milky Way. It also contains information about the size and the formation of our galaxy.

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

The 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

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 ^

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.
