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 $…
Ultra-light dark matter in disk galaxies
Nitsan Bar, Kfir Blum, Joshua Eby +1
Analytic arguments and numerical simulations show that bosonic ultra-light dark matter (ULDM) would form cored density distributions (`solitons') at the center of galaxies. ULDM so…
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…
