Andrés Escala – Structure Formation in the Universe: Small Scale Issues
“Structure Formation in the Universe: Small Scale Issues”
Universidad de Chile
When the cosmic microwave background came into 400.000 years after the big bang, the universe was almost perfectly uniform, with tiny density fluctuations that were the seeds of the galaxies and other structures we see today. I will review the standard theory of structure formation in the universe, based on Lambda-CDM cosmological paradigm, with special focus on the open issues on the smallest scales. I will discuss in detail problems currently studied by the theory group at Calan, such as cosmological massive black hole formation and star formation laws in galaxies.
