Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

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 …

We revisit the one-loop correction in curvature perturbation power spectrum in models of
single field inflation which undergo a phase of ultra slow-roll (USR) inflation. We include the …

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 …

Using the δN formalism we calculate the one-loop correction to the large-scale power
spectrum of the curvature perturbation in the standard scenario where primordial black holes …

We derive analytic bounds on the shape of the primordial power spectrum in the context of
single-field inflation. In particular, the steepest possible growth has a spectral index of ns …

We study the comoving curvature perturbation R in the single-field inflation models whose
potential can be approximated by a piecewise quadratic potential V (φ) by using the δ N …

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 investigate the sensitivity of the Laser Interferometer Space Antenna (LISA) to the
anisotropies of the Stochastic Gravitational Wave Background (SGWB). We first discuss the …
