Dipole Radiation and Kinetic Mixing from Dark Photon Solitons
Enrico D. Schiappacasse, Moira Venegas
Wave-like dark matter composed of spin-1 particles, known as dark photons, is theorized to form clumps called "vector solitons". These solitons are compact astrophysical objects th…
Dark photon dark matter from flattened axion potentials
Hong-Yi Zhang, Paola Arias, Andrew Cheek +3
Dark photons can be resonantly produced in the early universe via their coupling to an oscillating axion field. However, this mechanism typically requires large axion--dark photon…
Constraining Dark Photon Dark Matter with Radio Silence from Soliton Mergers around Supermassive Black Holes
Dorian W. P. Amaral, Enrico D. Schiappacasse, Hong-Yi Zhang
We place the first constraints on the dark matter fraction contained within dark photon solitons using the absence of their predicted radio-frequency signatures, or radio silence,…
Dark Spin-2 Field Solitons as a Source of Electromagnetic Radiation
Enrico D. Schiappacasse
Spin- light dark boson particles can exhibit wave-like behavior, capable of forming long-lived, coherent, spatially localized structures known as solitons. This work considers t…
