Galaxy Formation & Evolution
Tracing the assembly history of galaxies over cosmic time is a foremost goal in the exploration of the Universe. Indeed, galaxies are the building blocks of the Universe. They are the cradles for the formation of stars and black holes, but also serve as beacons that allow us to probe the geometry of space-time, the nature of dark matter and dark energy.
The field of galaxy formation and evolution concentrates on unveiling the origin of systems such as our Galaxy, the Milky Way, and the very wide diversity of the general galaxy population.
LASTRO particularly focuses on three aspects:
1) the conditions of formation and nature of the first stars, 300-500 Myr after the Big Bang
2) the assembly of galaxies, from the first systems (dwarf-like) to more massive ones
3) the coeval evolution of cosmic large scale structures and galaxies, and how, in this context, star formation is fuelled or quenched.
