Filtered Dark Matter at a First Order Phase Transition
Michael J. Baker, Joachim Kopp, Andrew J. Long
We describe a new mechanism of dark matter production in the early Universe, based on the dynamics of a first order phase transition. We assume that dark matter particles acquire m…
A phase of confined electroweak force in the early Universe
Joshua Berger, Andrew J. Long, Jessica Turner
We consider a modified cosmological history in which the presence of beyond-the-Standard-Model physics causes the weak gauge sector, , to confine before it is Hig…
X-ray Signatures of Axion Conversion in Magnetic White Dwarf Stars
Christopher Dessert, Andrew J. Long, Benjamin R. Safdi
White dwarf (WD) stars may radiate keV-energy axions produced in their stellar cores. This has been extensively studied as an extra channel by which WDs may cool, with some analyse…
Dark Photon Dark Matter from a Network of Cosmic Strings
Andrew J. Long, Lian-Tao Wang
We study the production of ultra-light dark photons from a network of near-global, Abelian-Higgs cosmic strings. We find that dark photons produced in this way are nonrelativistic…
