    What if the big bang was hotter than expected ?
    Researchers from UCLouvain, in collaboration with Caltech (United States) and the Max Planck Institute for Physics (Germany), have just proposed a new way to tell the story of the universe’s beginnings. Their model challenges the idea of a cold and empty Big Bang: according to them, the universe was “hot” from its very first fractions of a second thanks to a particle called the axion.

    Discovery of an ultra-high-energy particle (neutrino)
    Every second, trillions of neutrinos pass through each of us. These extremely abundant particles give astrophysicists a new lens to better understand our cosmos.
The UCLouvain Centre for Cosmology, Particle Physics and Phenomenology (CP3) hosts research on high energy particle physics, cosmology, phenomenology and theory of the fundamental interactions. It is strong on both the experimental and theoretical fronts. The aim of the Centre is to bring together researchers in these scientific fields and to encourage collaboration. You'll find below links to the details of our main research directions and the related projects.
