Dynamics of tidal spiral arms: Machine learning-assisted identification of equations and application to the Milky Way

[Context] 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 galaxy (Sgr), could play a significant role in exciting them.
