Resolving local and global kinematic signatures of satellite mergers with billion particle simulations
Jason A. S. Hunt, Ioana A. Stelea, Kathryn V. Johnston +3
In this work we present two new particle self-consistent simulations of the merger of a Sagittarius-like dwarf galaxy with a Milky Way-like disc galaxy. One model is a v…
Galactic Bar Resonances Inferred from Kinematically Hot Stars in Gaia EDR3
Daisuke Kawata, Junichi Baba, Jason A. S. Hunt +5
Using a numerical simulation of an isolated barred disc galaxy, we first demonstrate that the resonances of the inner bar structure induce more prominent features in the action spa…
The power of co-ordinate transformations in dynamical interpretations of Galactic structure
Jason A. S. Hunt, Kathryn V. Johnston, Alex R. Pettitt +3
DR2 has provided an unprecedented wealth of information about the positions and motions of stars in our Galaxy, and has highlighted the degree of disequilibria in the disc.…
The Strength of the Dynamical Spiral Perturbation in the Galactic Disk
Anna-Christina Eilers, David W. Hogg, Hans-Walter Rix +4
The mean Galactocentric radial velocities of luminous red giant stars within the mid-plane of the Milky Way reveal a spiral signature, which could plaus…
Searching for Solar Siblings in APOGEE and DR2 with N-body Simulations
Jeremy J. Webb, Natalie Price-Jones, Jo Bovy +4
We make use of APOGEE and data to identify stars that are consistent with being born in the same association or star cluster as the Sun. We limit our analysis to stars that…
In Pursuit of Galactic Archaeology: Astro2020 Science White Paper
Melissa Ness, Jonathan Bird, Jennifer Johnson +30
The next decade affords tremendous opportunity to achieve the goals of Galactic archaeology. That is, to reconstruct the evolutionary narrative of the Milky Way, based on the empir…
