We review numerous arguments for primordial black holes (PBHs) based on observational
evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This …

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 …

We report the most sensitive upper limits to date on the 21 cm epoch of reionization power
spectrum using 94 nights of observing with Phase I of the Hydrogen Epoch of Reionization …

Gravitational waves (GWs) generate oscillating electromagnetic effects in the vicinity of
external electric and magnetic fields. We discuss this phenomenon with a particular focus on …

We present cosmological parameter results from the final full-mission Planck measurements
of the CMB anisotropies. We find good consistency with the standard spatially-flat 6 …

We present the final nine-year maps and basic results from the Wilkinson Microwave
Anisotropy Probe (WMAP) mission. The full nine-year analysis of the time-ordered data …

We present the VLA-COSMOS 3 GHz Large Project based on 384 h of observations with the
Karl G. Jansky Very Large Array (VLA) at 3 GHz (10 cm) toward the two square degree …

Abstract Recently, the Hydrogen Epoch of Reionization Array (HERA) has produced the
experiment's first upper limits on the power spectrum of 21 cm fluctuations at z∼ 8 and 10 …

Light primordial black holes may comprise a dominant fraction of the dark matter in our
Universe. This paper critically assesses whether planned and future gravitational wave …

This biennial Review summarizes much of particle physics. Using data from previous
editions, plus 2158 new measurements from 551 papers, we list, evaluate, and average …
