We review recent trends in inflationary dynamics in the context of viable modified gravity
theories. After providing a general overview of the inflationary paradigm emphasizing on …

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 …

The recently released data by pulsar timing array (PTA) collaborations present strong
evidence for a stochastic signal consistent with a gravitational-wave background. Assuming …

This white paper summarizes recent progress in the cosmological bootstrap, an approach to
the study of the statistics of primordial fluctuations from consistency with unitarity, locality and …

We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic
microwave background (CMB) anisotropy measurements. The results are fully consistent …

We study gravitational waves (GWs) induced by non-Gaussian curvature perturbations. We
calculate the density parameter per logarithmic frequency interval, Ω GW (k), given that the …

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 analyse the Planck full-mission cosmic microwave background (CMB) temperature and
E-mode polarization maps to obtain constraints on primordial non-Gaussianity (NG). We …

The Square Kilometre Array (SKA) is a planned large radio interferometer designed to
operate over a wide range of frequencies, and with an order of magnitude greater sensitivity …

The search for the curl component (B mode) in the cosmic microwave background (CMB)
polarization induced by inflationary gravitational waves is described. The canonical single …
