We survey the prospective sensitivities of terrestrial and space-borne atom interferometers to
gravitational waves generated by cosmological and astrophysical sources, and to ultralight …

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 …

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

Ultralight dark matter exhibits an order-one density fluctuation over the spatial scale of its
wavelength. These fluctuations gravitationally interact with gravitational wave …

Matter-wave interferometers have fundamental applications for gravity experiments such as
testing the equivalence principle and the quantum nature of gravity. In addition, matter-wave …

Dark compact objects (“clumps”) transiting the Solar System exert accelerations on the test
masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of these …

In our recent companion paper [Fedderke et al. Phys. Rev. D 104, 075023 (2021) PRVDAQ
2470-0010 10.1103/PhysRevD. 104.075023], we pointed out a novel signature of ultralight …

We derive purely gravitational constraints on dark matter and cosmic neutrino profiles in the
solar system using asteroid (101955) Bennu. We focus on Bennu because of its extensive …

We point out that dark matter which is produced non-adiabatically in a phase transition (PT)
with fast bubble walls receives a boost in velocity which leads to long free-streaming …

We evaluate the potential for gravitational-wave (GW) detection in the frequency band from
10 nHz to 1 μ Hz using extremely high-precision astrometry of a small number of stars. In …
