We survey the prospective sensitivities of terrestrial and space-borne atom interferometers (AIs) to gravitational waves (GWs) generated by cosmological and astrophysical sources, and to ultralight dark matter. We discuss the backgrounds from gravitational gradient noise (GGN) in terrestrial detectors, and also binary pulsar and asteroid backgrounds in space-borne detectors. We compare the sensitivities of LIGO and LISA with those of the 100m and 1km stages of the AION terrestrial AI project, as well as two options for the proposed AEDGE AI space mission with cold atom clouds either inside or outside the spacecraft, considering as possible sources the mergers of black holes and neutron stars, supernovae, phase transitions in the early Universe, cosmic strings and quantum fluctuations in the early Universe that could have generated primordial black holes. We also review the capabilities of AION and AEDGE for detecting coherent waves of ultralight scalar dark matter.

  1. Gravitational wave signatures of primordial black hole accretion during early matter domination

    hep-ph 2025-05 conditional novelty 6.0 of 10

    PBHs that form in a radiation era and accrete during an early matter era could produce a two-peak GW background detectable by LISA or BBO for asteroid-mass PBHs as all of dark matter.

  2. Gravitational Waves from Spectator Scalar Fields

    hep-ph 2025-06 conditional novelty 4.0 of 10

    Heavy spectator scalar fields with masses near the inflationary Hubble scale generate a gravitational wave background observable across pulsar timing arrays, LISA, and ground-based interferometers, with constraints re...
