N2 - Recent BICEP/Keck data on the cosmic microwave background, in combination with previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar perturbation spectrum, Formula Presented, as well as the tensor-to-scalar ratio, Formula Presented. These constrain the number of Formula Presented-folds of inflation, Formula Presented, the magnitude of the inflaton coupling to matter, Formula Presented, and the reheating temperature, Formula Presented, which we evaluate in attractor models of inflation as formulated in no-scale supergravity. The 68% C.L. region of Formula Presented favors large values of Formula Presented, and Formula Presented that are constrained by the production of gravitinos and supersymmetric dark matter.
