Phase-Spirals Across Galactic Disks II: Using large-scale "macro-spirals" in phase-spiral amplitude to derive perturbation times

Kiyan Tavangar, Kathryn V. Johnston, Jason A. S. Hunt +3

Phase-space spirals in the Milky Way disk are a key observable remnant of recent perturbations to the Galaxy. They provide insight into the disk's potential, dynamical evolution, p…

Dynamical Origins of Azimuthal Metallicity Variations in the Galactic Disk: Insights from Kinematic Ridges with Gaia

Carlos Jurado, Keith Hawkins, Jason A. S. Hunt +4

Kinematic and spectroscopic studies in the past few years have revealed coherent azimuthal metallicity variations across the Milky Way's disk that may be the result of dynamical pr…

Weighing the Milky Way's Satellite Galaxies Using Pulsar Accelerations

Thomas Donlon, Sukanya Chakrabarti, Jason A. S. Hunt

The properties of dwarf galaxies orbiting the Milky Way (MW) are useful for testing models of the formation of our Galaxy, and by extension various theories of cosmology. Recent ef…

The dark matter wake of a galactic bar revealed by multichannel Singular Spectral Analysis

Jason A. S. Hunt, Michael S. Petersen, Martin D. Weinberg +7

The Milky Way is known to contain a stellar bar, as are a significant fraction of disc galaxies across the universe. Our understanding of bar evolution, both theoretically and thro…

The phase spiral's origin and evolution: indications from its varying properties across the Milky Way disk

Axel Widmark, Kiyan Tavangar, Josh Kalish +2

The phase spiral is a perturbation to the vertical phase-space distribution of stars in the Milky Way disk. We study the phase spiral's properties and how they vary with spatial po…

Formation of the Two-Armed Phase Spiral from Multiple External Perturbations

Junxian Lin, Zhao-Yu Li, Rui Guo +3

Recent studies using the Gaia DR3 data have revealed a two-armed phase spiral in the phase space in the inner disk. In this study, we present new features of the two-armed…

Shaping the Milky Way: The interplay of mergers and cosmic filaments

Arpit Arora, Nicolás Garavito-Camargo, Robyn E. Sanderson +12

The large-scale morphology of Milky Way (MW)-mass dark matter (DM) halos is shaped by two key processes: filamentary accretion from the cosmic web and interactions with massive sat…

Milky Way dynamics in light of Gaia

Jason A. S. Hunt, Eugene Vasiliev

The Gaia mission has triggered major developments in the field of Galactic dynamics in recent years, which we discuss in this review. The structure and kinematics of all Galactic c…

The Milky Way's rowdy neighbours: The effects of the Large Magellanic Cloud and Sagittarius Dwarf on the Milky Way Disc

Ioana A. Stelea, Jason A. S. Hunt, Kathryn V. Johnston

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 domin…
