Random Fields on the Sphere presents a comprehensive analysis of isotropic spherical
random fields. The main emphasis is on tools from harmonic analysis, beginning with the …

The Planck nominal mission cosmic microwave background (CMB) maps yield
unprecedented constraints on primordial non-Gaussianity (NG). Using three optimal …

This review is devoted to recent developments in the statistical analysis of spherical data,
strongly motivated by applications in cosmology. We start from a brief discussion of …

We risk reaching false scientific conclusions if we test our physical theories against subsets
of the Gaia catalogue without correcting for the biased process by which stars make it into …

The eternal inflation scenario predicts that our observable Universe resides inside a single
bubble embedded in a vast inflating multiverse. We present the first observational tests of …

In the picture of eternal inflation, our observable universe resides inside a single bubble
nucleated from an inflating false vacuum. Many of the theories giving rise to eternal inflation …

The Planck space mission has observed the first three rotational lines of emission of Galactic
carbon monoxide (CO). Those maps, however, are either noisy or contaminated by …
