Abstract: The Cosmology Large Angular Scale Surveyor (CLASS) aims to characterize the primordial gravitational waves at the level of tensor-to-scalar ratio of 0.01, and make a cosmic-variance-limited measurement of the optical depth to reionization. CLASS is an array of four …

Abstract: Direct detection experiments create the most radioactively quiet spots on earth, to reveal collisions between dark and ordinary matter. XENON1T, the most sensitive such experiment currently, will soon be succeeded by LZ and XENONnT. This talk highlights XENON1T's recent …
