There is no other galaxy that can be studied in as much detail as our own Milky Way. Only here can we study individual stars in great detail, both in their chemical abundance patterns and also in their kinematic and astrometric properties. By searching for distinct kinematic and chemical signatures, we can infer what the Galaxy was like at early times.

We are currently experiencing a revolution in the field of Galactic Archeology as a result of the Gaia mission as well as several large scale spectroscopic surveys (including multi-object spectrographs like WEAVE and 4MOST) that are either already ongoing or set to begin in the near future.

In this splinter session, we aim to bring together the German community working on various topics related to Galactic Archaeology (both theoretical and observational). Relevant topics include (but are not limited to):

  • chemical abundance trends and kinematics of the bulge, disk and halo (observations and simulations)
  • dwarf galaxies, stellar streams and substructure in the halo
  • metal-poor stars
  • (future) spectroscopic surveys and Gaia

Each of these individual topics (amongst others) are important to our understanding of the processes involved in formation and evolution of our Galaxy, but bringing them all together and placing them in context with each other is crucial in order to gain a big picture understanding of the (early) history of the Milky Way.

Graduate students are especially encouraged to apply.
