The Astrophysical JournalWe 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

A Wave-corrected Assessment of the Local Midplane
The Astrophysical JournalAs 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

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

Phase Spirals across Galactic Disks. I. Exploring Dynamical Influences on Winding
The Astrophysical JournalThe vertical phase-space spirals in the Milky Way are clear evidence of disequilibrium. However, they are challenging to study because phase mixing signals evolve under the influence of many different dynamical processes and can be driven by many sources

Observational Constraints of Radial Migration in the Galactic Disk Driven by the Slowing Bar
The Astrophysical Journal LettersRadial migration is an important dynamical effect that has reshaped the Galactic disk, but its origin has yet to be elucidated. In this work, we present evidence that resonant dragging by the corotation of a decelerating bar could be the main driver of ...
