Andrés Escala – Structure Formation in the Universe: Small Scale Issues


“Structure Formation in the Universe: Small Scale Issues”

Andrés Escala

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.
