| Abstract | |
Unveiling the driving mechanisms behind galaxy growth is one of the main goals of Astrophysics, from the tiniest ultra-faint dwarfs in the Local Group to the most luminous blue galaxies beyond the epoch of reionization. In this thesis, we combine observations of Galactic halo stars from Gaia space mission and large-scale spectroscopic surveys to study the stellar populations of tidally disrupted dwarf galaxies that merged with the Milky Way during its process of hierarchical assembly. Overall, we cover a stellar mass range of 10^7 < M*/M < 10^9 within a redshift interval of 0.5 < z < 2.0. This thesis compiles papers either published (Limberg et al., 2021a, 2022, 2023, 2024) or submitted during the period of this PhD program (20202024). (AU) | |
