DESCRIPTION:Speakers: Yassin Rany Khalil (UNIFI)\n\n\n\nGaia has revealed 
 the details of the non-axisymmetric velocity field of the Milky Way disk i
 n unprecedented detail. However\, devising a precise model of the underlyi
 ng non-axisymmetric Galactic components is far from trivial. In this talk\
 , I will present my approach to this problem\, enabling the first-ever dir
 ect fit of a realistic non-axisymmetric Galactic dynamical model — with 
 a bar and two spiral modes — to the velocity field as measured with Gaia
 . I will then focus on the details of this model\, its limitations\, and o
 ngoing improvements. I will also discuss its applications\, with recent ex
 amples including Galactic tides in the Solar System and the influence of t
 he Galactic bar on the stellar halo and its tracers.\n \n\nJoin Zoom Meet
