DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IPHT-PHM/26/
 ">Stellar Dynamics in Galactic Nuclei</a>\nby Jean-Baptiste Fouvry (CNRS\,
  Institut d'Astrophysique de Paris) as part of Séminaire de physique math
 ématique IPhT\n\nLecture held in Salle Claude Itzykson\, Bât. 774\, Orme
  des Merisiers.\n\nAbstract\nMost galaxies harbor a supermassive black hol
 e in their centre around which orbits a stellar cluster\, the galactic nuc
 leus. The unique proximity of the Milky-Way's central black hole\, SgrA*\,
  offers an extraordinary opportunity to study such a crowded environment. 
 Although galactic nuclei are among the densest stellar systems in the univ
 erse\, the steep potential well generated by the central black hole allows
  for efficient long-term orbit-averaged interactions between the stars.\n\
 nUltimately\, this drives the relaxation of the stellar orbits through an 
 intricate hierarchy of dynamical processes. In this presentation\, I will 
 report on recent developments in kinetic theory\, describe efficient numer
 ical methods to simulate these dynamics\, and present first quantitative a
 pplications of these frameworks to constrain SgrA*'s stellar content.\n
