Planck isocurvature constraint on primordial black holes lighter than a kiloton
The episode discusses a paper titled "Planck isocurvature constraint on primordial black holes lighter than a kiloton." The hosts analyze how Planck data constrains light primordial black holes by examining isocurvature perturbations generated during their evaporation. They conclude that these constraints are tight, especially when considering the role of primordial non-Gaussianity.
