Cosmology is at a crossroad. Are the rising observational tensions harbingers of doom for our beloved LCDM paradigm? Is the young field of gravitational wave astronomy about to revolutionize our understanding of black holes, and their cosmic dynamics? What is the best explanation of the early universe? What are the most exciting new ideas? This annual workshop brings together leaders from our three institutes and beyond to address these questions, and plan a roadmap to advance the cosmological frontiers of fundamental physics.
