Accreted Globular Clusters in External Galaxies: Why Adaptive Dynamics is not the Solution
Sophia Lilleengen, Wilma H. Trick, Glenn van de Ven
Many astrophysical and galaxy-scale cosmological problems require a well determined gravitational potential which is often modeled by observers under strong assumptions. Globular c…
The globular cluster system of the Auriga simulations
Timo L. R. Halbesma, Robert J. J. Grand, Facundo A. Gómez +5
We investigate whether the galaxy and star formation model used for the Auriga simulations can produce a realistic globular cluster (GC) population. We compare statistics of GC can…
Identifying resonances of the Galactic bar in Gaia DR2: I. Clues from action space
Wilma H. Trick, Francesca Fragkoudi, Jason A. S. Hunt +2
Action space synthesizes the orbital information of stars and is well-suited to analyse the rich kinematic substructure of the disc in the \emph{Gaia} DR2 radial velocity sample (R…
Signatures of resonance and phase mixing in the Galactic disc
Jason A. S. Hunt, Mathew W. Bub, Jo Bovy +3
Gaia DR2 has provided an unprecedented wealth of information about the kinematics of stars in the Solar neighbourhood, and has highlighted the degree of features in the Galactic di…
On the ridges, undulations & streams in Gaia DR2: Linking the topography of phase-space to the orbital structure of an N-body bar
F. Fragkoudi, D. Katz, W. Trick +7
We explore the origin of phase-space substructures revealed by the second Gaia data release in the disc of the Milky Way, such as the ridges in the - plane, the undulations…
Dynamical heating across the Milky Way disc using APOGEE and
J. Ted Mackereth, Jo Bovy, Henry W. Leung +14
The kinematics of the Milky Way disc as a function of age are well measured at the solar radius, but have not been studied over a wider range of Galactocentric radii. Here, we meas…
