Fredagskollokvium: Cosmology and formation of structures
Clement Stahl, Pontificia Universidad Católica de Valparaíso, Chile
I will discuss about our current cosmological model with a bird's eye view. I will introduce some of the basic observational pillars of the paradigm: an expanding universe, primordial nucleosynthesis and the cosmic microwave background which is the first “picture” of our universe, when it was 380 000 years old.
Then, I will describe how structures such as galaxies and clusters of galaxies could form. I will eventually briefly discuss my own humble contribution to the field.
