No cosmological constraints on dark photon dark matter from resonant conversion: Impact of nonlinear plasma dynamics
Anson Hook, Junwu Huang, Mohamad Shalaby
We revisit and invalidate all dark photon dark matter constraints from resonant conversion of dark photons into photons (plasmons) in the early universe. These constraints rely on…

Patchy Screening of the CMB from Dark Photons
Dalila Pîrvu, Junwu Huang, Matthew C. Johnson
We study anisotropic (patchy) screening induced by the resonant conversion of cosmic microwave background (CMB) photons into dark-sector massive vector bosons (dark photons) as the…

Searching for String Bosenovas with Gravitational Wave Detectors
Dawid Brzeminski, Anson Hook, Junwu Huang +1
We study the phenomenology of string bosenova explosions in vector superradiance clouds around spinning black holes, focusing on the observable consequences in gravitational wave d…
