A Two-stage Settling of the Milky Way Disk Revealed by Precise ChronoGal Ages
The Astrophysical Journal LettersThe spatial distribution of Galactic disk stars of different ages and metallicities encodes its dynamical evolution history and formation pathways. The lack of precise ages for large, representative samples of stars has traditionally been a drawback for ...

Metallicity Mapping of the Ionized Diffuse Gas at the Milky Way Disk–Halo Interface
The Astrophysical JournalMetals in the diffuse, ionized gas at the boundary between the Milky Way’s interstellar medium (ISM) and circumgalactic medium, known as the disk–halo interface (DHI), are valuable tracers of the feedback processes that drive the Galactic fountain ...

Rotation and mass in the Milky Way and spiral galaxies [PDF]
Publications of the Astronomical Society of Japan, 2016 Abstract Rotation curves are the basic tool for deriving the distribution of mass in spiral galaxies. In this review, we describe various methods to measure rotation curves in the Milky Way and spiral galaxies. We then describe two major methods to calculate the mass distribution using the rotation curve.

The Astrophysical JournalIntergalactic 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.

Constraining the Geometry of Galactic Dark Matter with Gaia Data Release 3
The Astrophysical JournalWe 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 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.
