A non-axisymmetric potential for the Milky Way disk
Y. R. Khalil, B. Famaey, G. Monari +9
We provide a purely dynamical global map of the non-axisymmetric structure of the Milky Way disk. For this, we exploit the information contained within the in-plane motions of disk…
Gaia DR3 features of the phase spiral and its possible relation to internal perturbations
Chengdong Li, Arnaud Siebert, Giacomo Monari +2
Disc stars from the Gaia DR3 RVS catalogue are selected to explore the phase spiral as a function of position in the Galaxy. The data reveal a two-armed phase spiral pattern in the…
Constraining the Milky Way halo kinematics via its Linear Response to the Large Magellanic Cloud
Simon Rozier, Benoit Famaey, Arnaud Siebert +3
We model the response of spherical, non-rotating Milky Way (MW) dark matter and stellar halos to the Large Magellanic Cloud (LMC) using the matrix method of linear response theory.…
Resonant and non-resonant relaxation of globular clusters
Jean-Baptiste Fouvry, Chris Hamilton, Simon Rozier +1
Globular clusters contain a finite number of stars. As a result, they inevitably undergo secular evolution (`relaxation') causing their mean distribution function (DF) to evolve on…
The Kinematic Richness of Star Clusters - II. Stability of Spherical Anisotropic Models with Rotation
Philip G. Breen, Simon Rozier, Douglas C. Heggie +1
We study the bar instability in collisionless, rotating, anisotropic, stellar systems, using N-body simulations and also the matrix technique for calculation of modes with the pert…
Perturbed distribution functions with accurate action estimates for the Galactic disc
H. Al Kazwini, Q. Agobert, A. Siebert +8
In the Gaia era, understanding the effects of the perturbations of the Galactic disc is of major importance in the context of dynamical modelling. In this theoretical paper we exte…
Mapping the stability of stellar rotating spheres via linear response theory
Simon Rozier, Jean-Baptiste Fouvry, Philip G. Breen +3
Rotation is ubiquitous in the Universe, and recent kinematic surveys have shown that early type galaxies and globular clusters are no exception. Yet the linear response of spheroid…
Structure Formation and Microlensing with Axion Miniclusters
Malcolm Fairbairn, David J. E. Marsh, Jérémie Quevillon +1
If the symmetry breaking responsible for axion dark matter production occurs during the radiation-dominated epoch in the early Universe, then this produces large amplitude perturba…
