Tremaine-Gunn Control: Evading Bounds on Light Fermion Dark Matter

Joel Barir, Diego Blas, Anubhav Mathur +1

Pauli exclusion is often regarded as imposing a model-independent lower bound on the mass of fermionic dark matter in galaxies. We show that dark-sector interactions can substantia…

Low-Frequency Gravitational Bremsstrahlung and Memory in a Medium

Diego Blas, Silvia Gasparotto, Hitoshi Murayama +2

Gravitational radiation from the early Universe offers a powerful window into physics beyond the Standard Model (SM). In this paper, we investigate the low-frequency tail of gravit…

Technical Proposal for the Atom Interferometer CERN Experiment (AICE) Facility

Gianluigi Arduini, Nadja Augst, Mark G. Bason +79

We present the technical proposal for the Atom Interferometer CERN Experiment (AICE), a m vertical atom interferometer to be installed against the wall of the PX…

Gravitational waves decay in vacuum

Diego Blas, José Antonio Oller

We show that gravitational waves (GW), treated as coherent graviton states, decay into photon pairs in vacuum. The process, even if suppressed by , is lifted by two effects co…

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…

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…
