Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

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 …

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 …

We analyze cosmic superstring models in light of NANOGrav 15-year pulsar timing data. A
good fit is found for a string tension G μ∼ 10-12–10-11 and a string intercommutation …

This Horizon Study describes a next-generation ground-based gravitational-wave
observatory: Cosmic Explorer. With ten times the sensitivity of Advanced LIGO, Cosmic …

The NANOGrav Collaboration has recently published strong evidence for a stochastic
common-spectrum process that may be interpreted as a stochastic gravitational wave …

Pulsar timing data used to provide upper limits on a possible stochastic gravitational wave
background (SGWB). However, the NANOGrav Collaboration has recently reported strong …

We give a detailed treatment of electromagnetic signals generated by gravitational waves
(GWs) in resonant cavity experiments. Our investigation corrects and builds upon previous …

We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a
hypothesis that the data contains more than one population of black holes. We perform a …

MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to
explore fundamental physics with atom interferometry over a 100 m baseline. This novel …
