Stellar streams for Galactic and cosmic archaeology

Les courants stellaires pour l'archéologie galactique et cosmique La mission astrométrique Gaia a permis l'étude à grande échelle des étoiles et des sous-structures galactiques. Environ 160 amas globulaires (AG) de la Voie lactée, chacun contenant de centaines de milliers à plusieurs millions d'étoiles, peuvent désormais être ...

The GALAH Survey and Galactic Archaeology in the next decade

, 2015
The field of Galactic Archaeology aims to understand the origins and evolution of the stellar populations in the Milky Way, as a way to understand galaxy formation and evolution in general. The GALAH (Galactic Archaeology with HERMES) Survey is an ambitious Australian-led project to explore the Galactic history of star formation, chemical evolution ...

Galactic Archaeology in the Era of Large Surveys

, 2020
In this Thesis, I study the formation and chemical evolution of the Milky Way by means of new and detailed chemical evolution models in the light of the most recent data from Galactic surveys and missions. Indeed, we are in a golden era for Galactic Archaeology thanks to the advent of several Galactic spectroscopic surveys and missions.
