Galactic magnetic fields seeded by ultralight dark photons
Joshua Berger, Amit Bhoonah, Joseph Bramante +3
In this work, we show that ultralight dark photons, which couple to the Standard Model photon through kinetic mixing, can potentially source galactic scale magnetic fields. Althoug…

Dimming Starlight with Dark Compact Objects
Joseph Bramante, Melissa D. Diamond, J. Leo Kim
We demonstrate a new technique to search for dark compact objects. When dark matter comprising a dark compact object interacts with photons, the compact object can disperse light t…

Dissipative Dark Cosmology: From Early Matter Dominance to Delayed Compact Objects
Joseph Bramante, Christopher V. Cappiello, Melissa D. Diamond +3
We demonstrate a novel mechanism for producing dark compact objects and black holes through a dark sector, where all the dark matter can be dissipative. Heavy dark sector particles…
