GUEST: Gravitational Universe Exploration with Satellite Tracking. A passive satellite laser-ranging mission for the dark gravitational Universe
Diego Blas, Aurélien Hees, F. Javier Atapuerca +78
GUEST is a space mission concept whose central objective is the detection of gravitational waves (GWs) in the microhertz band -- a physics-rich frequency window that no other prese…
Unveiling the Microhertz Gravitational-Wave Sky with the Square Kilometre Array Observatory
Alexander C. Jenkins, Diego Blas, Joshua W. Foster
The gravitational-wave sky is expected to contain a rich variety of sources across a very broad range of frequencies. Much like in electromagnetic astronomy, exploring new gravitat…
Projecting the ultimate pulsar timing sensitivity to dark matter substructure in a stochastic gravitational wave background
Joshua W. Foster, Tanner Trickle, Fabrizio Vassallo
Pulsar timing arrays (PTAs) are sensitive to the gravitational influence of passing compact substructures, which can produce Doppler timing delays by accelerating pulsars or the So…
The Dark Side of the Moon: Listening to Scalar-Induced Gravitational Waves
D. Blas, J. W. Foster, Y. Gouttenoire +4
The collapse of large-amplitude primordial curvature perturbations into planetary-mass primordial black holes generates a scalar-induced gravitational wave background in the Hz…
Prospects for gravitational wave and ultra-light dark matter detection with binary resonances beyond the secular approximation
Joshua W. Foster, Diego Blas, Adrien Bourgoin +4
Precision observations of orbital systems have recently emerged as a promising new means of detecting gravitational waves and ultra-light dark matter, offering sensitivity in new r…
Discovering Hz gravitational waves and ultra-light dark matter with binary resonances
Joshua W. Foster, Diego Blas, Adrien Bourgoin +4
In the presence of a weak gravitational wave (GW) background, astrophysical binary systems act as high-quality resonators, with efficient transfer of energy and momentum between th…
