Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

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 …

The first direct measurement of gravitational waves by the LIGO and Virgo collaborations
has opened up new avenues to explore our Universe. This white paper outlines 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 …

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 …

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 present cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

We examine the possibility of Primordial Black Holes (PBHs) formation in single field models
of inflation. Using the adiabatic or wave function renormalization scheme in the short range …

We present a detailed exposition on the prospects of the formation of Primordial Black Holes
(PBHs) during Slow Roll (SR) to Ultra Slow Roll (USR) sharp transitions in the framework of …
