The Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) is a research institute that explores the fundamental questions and deep mysteries in the cosmos, from the smallest scale (such as high-energy particles and cosmic rays) to the biggest scale (such as the early Universe and large-scale structures). KIPAC houses 150+ scientists with diverse interests in astrophysics and cosmology, bringing the power of theory, computation, experiments, and observations to bear on the frontier questions in astronomy.
