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 …

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 cosmological principle (CP)—the notion that the Universe is spatially isotropic and
homogeneous on large scales—underlies a century of progress in cosmology. It is …

The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

We revisit the possibility that the stochastic common-spectrum process recently detected by
the NANOGrav pulsar timing array experiment could be due to primordial gravitational …

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 and …

Axions and other very light axion-like particles appear in many extensions of the Standard
Model, and are leading candidates to compose part or all of the missing matter of the …

The Simons Observatory (SO) is a new cosmic microwave background experiment being
built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the …

The collection of individually resolvable gravitational wave (GW) events makes up a tiny
fraction of all GW signals that reach our detectors, while most lie below the confusion limit …

This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …
