Dynamics of tidal spiral arms: Machine learning-assisted identification of equations and application to the Milky Way
Marcel Bernet, Pau Ramos, Teresa Antoja +4
Understanding the spiral arms of the Milky Way (MW) remains a key open question in galactic dynamics. Tidal perturbations, such as the recent passage of the Sagittarius dwarf galax…
Spiral arms across stellar populations in simulations via the local dimension method
J. Ardèvol, M. Semczuk, T. Antoja +3
Context. The origin and nature of spiral arms remain unclear. Star forming regions and young stars are generally strongly associated to the spiral structure, but there are few quan…
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…
Dark matter spiral arms in Milky Way-like halos
Marcel Bernet, Pau Ramos, Teresa Antoja +9
The coupling between the dark matter (DM) halo and the stellar disc is a key factor in galactic evolution. While the interaction between structures like the Galactic bar and DM hal…
