Over the past few decades, cosmology has made remarkable advancements, thanks to progress in observations and theoretical physics. Precise measurements of the anisotropies in the cosmic microwave background, the large-scale distribution of galaxies, detection of the gravitational waves have had, and will continue to have, a significant impact on cosmology, propelling it into the realm of precision.
This colloquium is organized on the occasion of Ruth Durrer being awarded the title of Doctor Honoris Causa in Toulouse by Paul Sabatier University. Ruth Durrer's work in theoretical cosmology has been instrumental in advancing our understanding of the fundamental principles and dynamics that govern the universe. Her contributions have significantly influenced the field and have had a profound impact on our comprehension of the cosmos, expanding our theoretical frameworks but also established valuable connections between different branches of physics. Her research has been pivotal in shaping the field of cosmology and has inspired numerous scientists to delve deeper into the mysteries of the cosmos. This event provides an opportunity to bring together individuals who have had the pleasure of interacting with Ruth, as well as those who are engaged in research topics related to her work.
