Global View of Axion Stars with (Nearly) Planck-Scale Decay Constants
Joshua Eby, Lauren Street, Peter Suranyi +1
We show that axion stars formed from axions with nearly Planck-scale decay constants are unstable to decay, and are unlikely to have phenomenological consequences. More general…
Galactic Condensates composed of Multiple Axion Species
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
Ultralight scalar dark matter has been proposed to constitute a component of dark matter, though the minimal scenarios have increasingly become constrained. In this work, we analyz…
Searching for Earth/Solar Axion Halos
Abhishek Banerjee, Dmitry Budker, Joshua Eby +4
We discuss the sensitivity of the present and near-future axion dark matter experiments to a halo of axions or axion-like particles gravitationally bound to the Earth or the Sun. T…
Global view of QCD axion stars
Joshua Eby, Madelyn Leembruggen, Lauren Street +2
Taking a comprehensive view, including a full range of boundary conditions, we reexamine QCD axion star solutions based on the relativistic Klein-Gordon equation (using the Ruffini…
Luminous Signals of Inelastic Dark Matter in Large Detectors
Joshua Eby, Patrick J. Fox, Roni Harnik +1
We study luminous dark matter signals in models with inelastic scattering. Dark matter that scatters inelastically off elements in the Earth is kicked into an excited state $…
Relaxion Stars and their detection via Atomic Physics
Abhishek Banerjee, Dmitry Budker, Joshua Eby +2
The cosmological relaxion can address the hierarchy problem, while its coherent oscillations can constitute dark matter in the present universe. We consider the possibility that th…
