Description

CMB-S4, the next-generation ground-based cosmic microwave background (CMB) experiment, will make measurements with unprecedented precision and provide fundamental new insights into cosmology and fundamental physics. Its key measurements will include the search for primordial gravitational waves, probes of the nature of dark matter and dark energy, tight constraints on light relic particles, mapping matter throughout the Universe, and the detection of transient events in the microwave sky. In this talk, I provide an overview of the CMB-S4 science program, highlighting the rich astrophysical measurements it will enable. I will also describe the instrument configuration and project status.
