All cosmological observations to date are consistent with adiabatic, Gaussian and nearly
scale invariant initial conditions. These findings provide strong evidence for a particular …

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 …

We identify a characteristic pattern in the scalar-induced stochastic gravitational wave
background from particle production during inflation. If particle production is sufficiently …

A bstract Cosmological correlation functions contain valuable information about the
primordial Universe, with possible signatures of new massive particles at very high energies …

All single-field inflationary models invoke varying degrees of tuning in order to account for
cosmological observations. Mechanisms that generate primordial black holes (PBHs) from …

We present the current accounting of systematic effect uncertainties for the Low Frequency
Instrument (LFI) that are relevant to the 2015 release of the Planck cosmological results …

This book lays out the scientific goals to be addressed by the next-generation ground-based
cosmic microwave background experiment, CMB-S4, envisioned to consist of dedicated …

The Planck full mission cosmic microwave background (CMB) temperature and E-mode
polarization maps are analysed to obtain constraints on primordial non-Gaussianity (NG) …

I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

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 …
