WDs and neutron stars are far-reaching and multi-faceted laboratories in the hunt for dark
matter. We review detection prospects of wave-like, particulate, macroscopic and black hole …

In this paper, which is of programmatic rather than quantitative nature, we aim to further
delineate and sharpen the future potential of the LISA mission in the area of fundamental …

Abstract The Einstein Telescope (ET), a proposed European ground-based gravitational-
wave detector of third-generation, is an evolution of second-generation detectors such as …

New Particles Beyond the Standard Model have always been thought to be charged under
at least some of the same gauge interactions of ordinary particles. Although this assumption …

We present a data analysis methodology for a model-independent reconstruction of the
spectral shape of a stochastic gravitational wave background with LISA. We improve a …

Exploring dark matter via observations of extreme astrophysical environments--defined here
as heavy compact objects such as white dwarfs, neutron stars, and black holes, as well as …

In this white paper, we discuss the prospects for characterizing and identifying dark matter
using gravitational waves, covering a wide range of dark matter candidate types and signals …

Light axion fields, if they exist, can be sourced by neutron stars due to their coupling to
nuclear matter, and play a role in binary neutron star mergers. We report on a search for …

The neutron lifetime anomaly has been used to motivate the introduction of new physics with
hidden-sector particles coupled to baryon number, and on which neutron stars provide …

We show that gravitational wave emission from neutron star binaries can be used to
discover any generic long-ranged muonic force due to the large inevitable abundance of …
