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 …

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 …

Various pulsar timing array (PTA) experiments (NANOGrav, EPTA, PPTA, CPTA, including
data from InPTA) very recently reported evidence for excess red common-spectrum signals …

Abstract LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation
from cosmic background Radiation Detection, is a space mission for primordial cosmology …

The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

We provide a review on the state-of-the-art of gravitational waves induced by primordial
fluctuations, so-called induced gravitational waves. We present the intuitive physics behind …

Gravitational wave (GW) detection in space probes the GW spectrum that is inaccessible
from the Earth. In addition to the LISA project led by the European Space Agency, and the …

The current cosmological model requires new physics beyond the standard model of
elementary particles and fields, such as dark matter and dark energy. Their nature is …

Gravitational waves are a unique probe of the early Universe, as the Universe is transparent
to gravitational radiation right back to the end of inflation. This review summarizes detection …
