  • what: The authors compare CMB maps observed by the Planck satellite with thousand simulated maps generated according to the ΛCDM paradigm with Gaussian distributed fluctuations. For Gaussian, and Gaussian-related random fields, the expected values of the Minkowski functionals of excursion sets have known analytic expressions (Adler . . .
