This review presents a comprehensive overview of galaxy bias, that is, the statistical relation
between the distribution of galaxies and matter. We focus on large scales where cosmic …

Cosmic inflation provides a window to the highest energy densities accessible in nature, far
beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the …

The formation and abundance of primordial black holes (PBHs) arising from the curvature
perturbation ζ is studied. The non-linear relation between ζ and the density contrast δ means …

Primordial black holes (PBHs) cannot be produced abundantly enough to be the dark matter
in canonical single-field inflation under slow roll. This conclusion is robust to local non …

Our current understanding of the Universe is established through the pristine measurements
of structure in the cosmic microwave background (CMB) and the distribution and shapes of …

A bstract Recent progress has revealed a number of constraints that cosmological
correlators and the closely related field-theoretic wavefunction must obey as a consequence …

Structure in the Universe is widely believed to have originated from quantum fluctuations
during an early epoch of accelerated expansion. Yet, the patterns we observe today do not …

Considering high-energy modifications of Einstein gravity during inflation is an interesting
issue. We can constrain the strength of the new gravitational terms through observations of …

We discuss new consistency relations for single field models of inflation capable of
generating primordial black holes (PBH), and their observational implications for CMB μ …

The large scale limit of the galaxy power spectrum provides a unique window into the early
Universe through a possible detection of scale dependent bias produced by primordial non …
