Conference

Reflecting on 10 years of collaboration with the Perimeter Institute, I will discuss one of many exciting cosmological probes opened up by high-resolution observations of the cosmic microwave background (CMB), the kinetic Sunyaev Zeldovich (kSZ) effect.  PI has and continues to serve as an incubator for novel approaches with this probe that will shed light on the initial conditions of the universe and the particle nature of dark matter.  Realizing the full potential of the kSZ effect requires new data.  I will report on new results from the Simons Observatory, a path-breaking CMB survey that recently saw first light.
