Non-axisymmetric perturbations, including internal spiral arms and bars and external perturbations by satellites, are among the main drivers of secular evolution of galaxies. Understanding these instabilities and their consequences on the chemo-dynamical evolution of galactic discs in general, and the Milky Way’s disc in particular, has been one of the hottest topics in the area of galactic dynamics for decades. In this context, classical perturbation theory is the best theoretical tool we have at hand to understand the complicated physics involved in these processes, and to address in a coherent way the secular chemo-dynamical evolution of the Galactic disc. In order to understand the role that non-axisymmetric perturbations have played in the history of the Galactic disc, it is important to constrain the details of the present-day non-axisymmetric perturbations of the disc. Such constraints can be obtained by analysing combined data from Gaia DR3 and the WEAVE spectroscopic survey.
We are seeking candidates with an expertise in modelling of the Galactic disc structure and dynamics, to work on perturbative models of the Galactic disc mono-age populations in angle-action space using Gaia and WEAVE data and on the interpretation of this model in the context of galactic archaeology and formation. This work will be performed in close collaboration with the WEAVE affiliated researchers at Strasbourg Astronomical Observatory as well as colleagues from Observatoire de la Cote d’Azur, Observatoire de Paris (GEPI) and the WEAVE LRdisc team.
