A short history of the Universe

09.12.2025 09:00 – 11:00

The cosmic microwave background (CMB) offers a remarkable window onto the early Universe, preserving the imprints of processes that took place just moments after the Big Bang. By studying subtle features in the CMB, we can search for signatures of high-energy physics, such as the remnants of cosmological phase transitions. At the same time, the CMB reveals much about the late-time Universe, helping us to probe the nature and dynamics of dark energy. In this talk, I will outline my main contributions to these topics – from modeling topological defects and dark energy to interpreting cosmological observations – and discuss how future missions, in particular ESA’s Euclid satellite, will deepen our understanding of the evolving Universe.
