Minicourse:
Early Universe Cosmology

November 14 - December 1, 2022

Tuesday and Thursday  -  10:00 - 12:00

Prof. Elisa Gouvêa Mauricio Ferreira

What happened in the first instants of our universe? How did all the we have in the universe was formed? Did the universe have a beginning?

In this minicourse we will present some of the advances in the field of cosmology to answer these questions. We will discuss the most well established and studied models and techniques to explain the first moments of our universe.

This minicourse is an introduction to the cosmology of the very early universe for graduate students that are starting their studies in theoretical cosmology or from correlated fields in theoretical physics. 

 

The study of the primordial universe uses many topics in theoretical physics like quantum field theory, particle physics, quantum mechanics, general relativity, condensed matter, quantum gravity, among others. The universe, more specific the early universe,  is the perfect laboratory for applying these research fields, so students and researchers from many fields of research in theoretical physics are welcome.
