Ana Achúcarro Group - The Early Universe
We explore the particle physics and quantum world at the time of the big bang.
We connect high energy physics and quantum theory to observations of the microwave background radiation and the distribution of galaxies and matter in the universe. This way, we research the initial conditions of the early universe, including cosmic inflation, trying to identify possible relics of phase transitions of other violent events.
