Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

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 …

Cosmic Explorer is a concept for a new laser interferometric observatory in the United States
to extend ground-based gravitational-wave astrophysics into the coming decades. Aiming to …

Galactic compact binaries with orbital periods shorter than a few hours emit detectable
gravitational waves (GWs) at low frequencies. Their GW signals can be detected with the …

Galactic nuclei harbouring a central supermassive black hole (SMBH), possibly surrounded
by a dense nuclear cluster (NC), represent extreme environments that house a complex …

Gravitational-wave (GW) astronomy is transforming our understanding of the Universe by
probing phenomena invisible to electromagnetic observatories. A comprehensive …

Beyond individually resolvable gravitational wave events such as binary black hole and
binary neutron star mergers, the superposition of many more weak signals coming from a …

A major challenge for gravitational-wave (GW) detection in the μ Hz band is engineering a
test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept …

A new era of lunar exploration has begun bringing immense opportunities for science as
well. It has been proposed to deploy a new generation of observatories on the lunar surface …

Our Moon is by far the easiest natural, extraterrestrial celestial object for us to reach, and
many space agencies, in particular the China National Space Administration, have …
