Magnetic monopole plasma oscillations and implications for TeV blazars
Mariia Khelashvili, Takeshi Kobayashi, Andrew J. Long
Magnetic monopoles arise in many beyond Standard Model scenarios, symmetrize Maxwell's equations, and their existence would be tied to the quantization of electric charge. It has b…

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…
