SUMMARY:Chemical evolution in the Milky-Way and its satellites: an observat
 ional perspective
DESCRIPTION:Chemical evolution in the Milky-Way and its satellites: an obse
 rvational perspective\nVanessa Hill\n\nUnderstanding formation and evoluti
 on of galaxies on the galactic and sub-galactic scales is a key question t
 o modern astrophysics. The L-CDM concordant cosmology paradygm, sucessful 
 in predicting many large scale observables of the Universe, starts to fail
  at the galactic or sub-galactic scales (e.g., missing satellites problems
 , planes of satellites, central dark matter density profiles of galaxies, 
 etc.). The Milky Way, with its system of dwarf galaxy satelites, is the en
 vironment in which we can hope to constrain in most details the physical p
 rocesses that play a role in the formation and evolution of galaxies, enco
 ded in the location, kinematics and chemistry of individual stars, a field
  often referred to as Galactic Archaeology. Taking the example of the Scul
 ptor dwarf galaxy, for which a wealth of complementary data are available,
  from wide field photometry to sizeable spectroscopic samples, and now als
 o astrometric Gaia data, I will discuss our current observational understa
 nding of how chemical enrichment proceeds at the smalest scales. In t
 he context of the Gaia space mission and ground based large spectroscopic 
 surveys such as WEAVE@WHT,  Galactic Archaeology, is living a revolut
 ion. I will review some of the most prominent science cases for a Galactic
  Archaeology survey with the WEAVE wide field multi-object facility for th
 e WHT, and highlight how this complements the Gaia astrometric mission.&nb
