The reconstruction of the lensing bispectrum

CMB lensing is a powerful tool to test cosmological parameters, and coming ground-based experiments could potentially detect the lensing bispectrum with a high significance.

Fundamental limits on constraining primordial non-Gaussianity

In this work, we explore the cosmic variance limit on constraining primordial non-Gaussianity for a variety of theory-motivated shapes.

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

PBHs can be a probe of the physics of the early universe. Here, we provid new constraints on the primordial curvature power spectrum from the latest limits on PBH abundance.
