Fundamental limits on constraining primordial non-Gaussianity

Alba Kalaja, P. Daniel Meerburg, Guilherme L. Pimentel +1

We study the cosmic variance limit on constraining primordial non-Gaussianity for a variety of theory-motivated shapes. We consider general arguments for 2D and 3D surveys, with a…

From Primordial Black Holes Abundance to Primordial Curvature Power Spectrum (and back)

Alba Kalaja, Nicola Bellomo, Nicola Bartolo +5

In the model where Primordial Black Holes (PBHs) form from large primordial curvature (C) perturbations, i.e., CPBHs, constraints on PBH abundance provide in principle constraints…
