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…

Free streaming of warm wave dark matter in modified expansion histories
Andrew J. Long, Moira Venegas
In models of warm dark matter, there is an appreciable population of high momentum particles in the early universe, which free stream out of primordial over/under densities, thereb…

Setting up stasis with gravitational interactions
Andrew J. Long, Barmak Shams Es Haghi, Moira Venegas
An epoch known as cosmological stasis may have taken place in the early Universe. During matter-radiation stasis, a population of non-relativistic particles with different masses g…
